May 30, 1964 - The 48th running of the "Greatest Spectacle in Racing" - The Indianapolis 500. This page begins in October 1963 and offers
a chronological accounting of the 1964 Indy 500 from the Thompson Team's perspective.

Mickey Thompson hires sports car star Dave MacDonald to run one of his radical new low-slung racers in the '64 Indy 500.

Oct 1963 article regarding USAC rule change. After the '63 Indy 500 many car owners and drivers complained about Mickey Thompson's
low-slung race cars. USAC subsequently mandated all future 500's to be run on tires no smaller than 15". The ruling was a major setback
to Mickey as his cars were specifically designed to ride on the tiny low profile 12" tires originally approved by USAC. (NOTE: The article
mentions one of Mickey's rollerskates finishing 9th in the '63 500, it was actually Al Miller in a rear engine car with traditional size tires.)

This photo is from the garage area during the 1963 Indy 500 and shows the dramatic difference between Mickey Thompson's 12" slicks
that USAC banned after 1963, and some of the larger traditional Indy tires. [Dave Friedman/The Henry Ford]

Photos below are from the November 1963 tire test session at the Speedway. Testing scheduled for five days beginning on the 26th with
Dave MacDonald, Masten Gregory and Duane Carter on hand. These crucial first laps with the larger 15” tires would either ease or confirm
the team’s fears that the car’s taller stance would have a negative effect on handling. Below MacDonald sits in the 82 car with compliant 15"
rubber while Thompson checks the scales. [Dave Friedman/The Henry Ford]

With the Thompson 82 fired up Dave MacDonald is pushed to the track for the moment of truth. Notice the crude air intake mod taped to the
nose of the car. Mickey ran these cars with Chevrolet powerplants in '63 and while he’d contracted with Ford to run the new (and heavier)
’64 DOHC engines in '64 they were not available at the time of these tests. Mick at right rear helping push. [Dave Friedman/The Henry Ford]

Duane Carter takes his turn in the 82 car and is back in with a similar report, the car is lifting. A low center of gravity was a critical design
element in Mickey’s cars and now the team must begin searching for an on-track solution. [Dave Friedman/The Henry Ford]

Bottom line is the November tests were nothing short of disaster and Mickey cancelled the five day session after day two to go home to Long
Beach California and come up with a solution. Below is a November ‘63 blurb from Motor Trend writer George Moore's Indy Diary.

With the November tests cut short Dave had an unexpected break before his scheduled arrival in the Bahamas on 12/1 to run the King Cobra
for Shelby. He figured he'd fly home to California and spend the rest of Thanksgiving with his family. Ford had different plans and rerouted
him to Daytona to join Fred Lorenzen and the Holman Moody team to run tire tests on the new ’64 Ford Galaxy. He left Indy on the
28th aboard an Eastern Airlines flight for Miami and then puddle hopped to Daytona.

Dave (seated on wall by driver's door w/Shelby shirt underneath his sweater) met up with Fred Lorenzen (behind car) and the Holman Moody
team at Daytona Speedway and ran tire tests that evening and the next morning. On Nov 29th Dave left Daytona for Miami and the Bahamas.

Meanwhile Mickey Thompson had trailered both cars back to his Long Beach California speed shop and began chassis and suspension mod-
ifications in an effort to resolve handling issues posed by the larger tires. Photo courtesy Mickey & Danny Thompson

Dec 6, 1963 - Mickey Thompson describes the disappointing November test session to Los Angeles Times writer Bob Thomas. "The cars
just wouldn't handle, there was too much body roll due to the higher center of gravity". Mickey also says the cars are currently in a wind
tunnel. (who knew wind tunnel testing was available in '63?)

Mickey Thompson was not only a hard charger and brilliant innovator, but a charismatic salesman as well. Just a sophomore at Indy but
nonetheless able to secure three of Ford's powerful new double overhead cam engines - a hot commodity in the Ford camp. This from

Sherry MacDonald's notes from March 1964. Dave MacDonald flies back to the Brickyard for additional testing on the Thompson racers.
It will be a three day test session.

Dave and the Thompson team are on the track early on March 17th, Sears tire people were back too for a first hand look at hopeful progress
on Mickey's racers. The car were fitted with the new experimental aero modifications; which included side skirts and a rear wing but USAC
officials denied the use of those mods (Wings & sides skirts are commonplace today). Drivers present for these tests were Graham Hill,
Masten Gregory and Dave MacDonald. Only one new '64 DOHC Ford engine was made available for these tests and it went in the 82 car.
Dave's 83 still ran with a Chevy powerplant. After only a couple laps in the 83 Hill brought it in and parked it, calling it "diabolical". He
left Indy for Europe and did not return

Sears tire engineers performing tests after Masten Gregory's run. Gregory and MacDonald agreed with Graham Hill that handling issues
remained but both drivers felt an improvement and at this point at least would stay committed to the team.

Sherry's notes show Dave & Masten only managing low speeds at these March tests. Dave 135 mph with the lighter Chevrolet engine and
136 mph for Masten in the 82 car with a heavier Ford DOHC engine but also with newly installed lighter titanium suspension pieces. Tests
were discouraging but Mickey promised significant changes once he had the cars back at his Long Beach California speed shop.

Changes indeed! Mickey assembles the press on April 21 to show off his newly redesigned Ford Sears Allstate Special. He'd completely
redesigned the car from the inside out and skinned them with new full fendered aerodynamic body kits designed to counteract lifting
and floating caused by the larger 15" tires. Remarkably Mickey and his team accomplised this in a mere 30 days! [Bruce R Craig]

On April 22, 1964 the LA Times gives readers a first glimpse at Mickey Thompson's new full fendered aero design Indy car.

Four days later the El Monte Herald runs a photo and the southland is buzzing about Thompson's futuristic Indy car

May 1, 1964. The Brickyard officially opens for practice.

All eyes on Mickey Thompson's exotic full-fendered superskate as the team begins practice at the brickyard. Bright and early on May 1, the
Thompson #83 car (MacDonald's car) and Chuck Rodee's #87 are pushed out for some track time. In addition to the aero skins, there were
many other modifications made to the cars since the March tests, including major chassis & suspension adjustments all in an effort to
resolve instability issues. Mickey's rear wing attachments were still ruled out by USAC officials. Photo courtesy IMS.

Mickey Thompson's new design was a dramatic departure from the traditional open wheel Indy racer. Thompson was a brilliant innovator
and his aero kit's were far ahead of their time but still unproven on these cars, and at the Brickyard. To date only wind tunnel testing had
been performed but now rubber meets road and the question of whether or not the aero skins would counteract the lifting and floating caused
by the 15" tires would be answered. Dave MacDonald's #83 racer pushed to the pit area and readied for initial testing. [The Henry Ford]

Out next was Masten Gregory in Duane Carter's #82 car. [First Turn Productions]

Gregory returns from his practice run in the 82 and tells Mickey the car is not only not sticking in the corners but lifting in the straights too,
to the point where the steering was so light he didn't have control of the car. Mickey braced for a long month. #97 is Parnelli Jones in
JC Agajanian's rear engined car. On Dec 10 Jones made the decision to stick with the front engined #98. Photo The Henry Ford.

Throughout the day on May 1 the Thompson team made adjustments to the cars of Masten Gregory and Dave MacDonald and here the
team changes the setup on MacDonald's #83 car before sending him out again. The cars were far from where they hoped they'd be at
this point and the entire team realized it was going to be a trying month. Not many happy faces in this Dave Friedman photo.

Crowd favorite Eddie Sachs takes his American Red Ball Express Ford out for practice laps on May 2nd. Dave MacDonald in the Thompson
83 in the background will run practice laps too in preparation the first stage of his rookie tests later in the day.

““

Late in the afternoon on May 2nd it was time for Dave MacDonald to perform his rookie test. The cars remained in adjustment mode and
fortunately the rookie test was not at full speed. The test required drivers to run 10 consecutive laps around the track at a moderate, con-
sistent speed. A driver’s speed isn’t supposed to vary by more than half a mile an hour and is increased in increments of 5 mph: 120 mph,
125 mph, 130 mph and 135 mph. Many drivers have been sent home for more seasoning after failing to impress officials during their test.

After successfully completing his two day rookie testing Dave MacDonald removes his rookie stripe as Mickey Thompson and track safety
director Paul Johnson look on. Johnson and veteran USAC Director Jim Thompson were overseeing the testing process and both said they
were impressed with Dave. “He laid ’em in there very consistently,” said Thompson, “He’s a very good looking boy.” Photo IMS.

Rookie test aside, the crew knew that running at 130 mph is far different from side by side racing at 180 so they continued to look for a
setup that would provide speed as well as control. The Thompson crew would work on MacDonald's car while he flew back to California
to run a race for Carroll Shelby. Dave Friedman photo from the The Henry Ford Collection

Dave was becoming a Ford "Works" driver and having signed a 20-race NASCAR contract with factory member Bill Stroppe was scheduled
to run the Stroppe #17 Merc in the Yankee 400 at IRP on May 3rd. However having already skipped the Pensacola USRRC race in favor of
the Atlanta 500 NASCAR race Dave lost his lead in the USRRC Drivers standings to Pensacola winner Jim Hall. So Carroll Shelby pulled
rank to get Dave rerouted to Laguna Seca and run the King Cobra against Hall. Rodger Ward filled in and ran the 17 to a 7th place finish …
with Dave’s yellow rookie bumper and all!

Not known if this is the conversation where Agajanian offered Dave the ride for 1965 but he did so early in the month. At the time JC was
unaware Dave had signed a two-year contract with Thompson for '64 & '65.

Adding further controversy to Mickey's cars was Colin Chapman's discovery of a radical third-wheel steering arm connected to the right
rear wheel of Mickey's racers. This went completely unnoticed by track officials during car inspections. When this news hit the wires any-
one who wasn't already talking about the Thompson superskates, was now. Mickey was a brilliant innovator, and while many of his con-
cepts were revolutionary they didn't always receive proper development time. This was more of an experimental solution Mickey concocted
to help resolve the floating issues. By all accounts it was disconnected by race time.

Mickey brought in several different nose cone configurations from his Long Beach California speed shop in an effort to find a setup
that kept the car's from lifting in the front.

Dave MacDonald's #83 car gets fitted with a new front aero shell and is pushed from the garage to the painter to be numbered. A new rule
required all cars to be properly numbered before being put on the track. Mickey continued to believe USAC was trying to make his life
more difficult and says the impromptu ruling was aimed directly at him. Dave Friedman photo from the The Henry Ford Collection

Sign Mickey Thompson hung in his Indy garage. Mickey was already unhappy with USAC for banning his tiny 12" tires, and then for
disallowing the use of his rear wing and aero side skirts. He felt the Indy establishment was wholly against him and he was not shy about
expressing his feelings, often openly blasting USAC officials for costing him $250K in development costs. Photo The Henry Ford

May 6 blurb from Motor Trend writer George Moore's "Indy Diary" about how the Thompson crew had been out running yarn tuft tests with
MacDonald's #83 car. The crew stationed cameras at several points throughout the track to monitor and film the movement of the tufts.
Mickey also cut air vents into the tops of the front shells and was experimenting with various configurations in an effort to improve handling.

the press he's displeased with his ride. He also confides to good friend Jack Brabham that his Thompson car "Is the most lethal, evil
handling car I've ever driven". (Mickey Thompson far left and Dave MacDonald on pit wall to the right). [Dave Friedman/THF]

Sherry's notes told to her by Dave on May 6

Through at least May 7, Mickey had Dave do additional testing with the 82 car trying to sort the handling issues. They could only run a top
speed of 120 mph though as anything beyond that and the car was gone.

After hitting just 120MPH in the 82 car Dave MacDonald brings it back in and explains the problems to Mickey. (The Henry Ford)

At Kent Dave ran King Cobra CM/3/63 to victory outdueling Jim Hall and his mighty Chaparral - Dave invited Jim to share in the victory
lap. While at Kent, Dave confided to friends that Mickey's Indy car still was not right. Ken Miles, Bob Holbert, chief mechanic Wally Peat,
SAI photog Dave Friedman and Corvette legend Dick Guldstrand all urged him not to go back to Indy. Carroll Shelby told Dave he’d been
hearing reports the car needed more development. Carroll urged Dave not to run telling him he'd build him a Lotus for 1965, even offering
to call Mickey to tell him he wasn't coming back. Carroll says Dave “Would not hear it, any of it, he was a loyal man and he felt obliged to
Mickey for giving him the shot”. He told Carroll the crew was working hard on the cars and was confident they’d sort them out. After the
race Carroll sends Peat to Indy to get a firsthand account. [Dave Friedman/The Henry Ford].

but says he's had enough and leaves the Thompson team. Before storming off he tells Mickey he believes air getting trapped beneath the
enclosed fenders is the major factor in why the cars are so unstable.

With his wrecked #84 racer at his side a dejected Mickey Thompson ponders his next move. Meanwhile SAI chief mechanic Wally
Peat leaves Indianapolis. Wally was perhaps Dave's closest friend and felt strongly he should walk away from the Thompson car,
laying out his concerns one by one. Dave was adamant that he would stay on and see it through. The two friends argued and Wally
left Indy. It would be the last time the two would speak and a moment Wally has regreted to this day.

Gregory true to his word leaves the Thompson team and takes an open spot with the Dean Van Lines team. He begins to openly criticize
Mickey's race cars in the press.

Late in the day on May 17th Dave MacDonald is out practicing in between sporadic day 2 qualifying. He rounds turn 2 and the engine on
his Sears Allstate Ford gives out. The Thompson team tows Dave back to the garage. The team had no more engines available and a Ford
engineer told Mickey it would be days, maybe a week before Detroit could send another. Mickey was not allowed to use an engine from
the #82 & 84 cars as Detroit made it clear the priority was to keep them running and get them in the field too. MacDonald wanted the
track time but with nothing to do he flew back to California later that evening to be with his family. Photo Indianapolis Motor Speedway

Still down a racer after Gregory's departure, Mickey Thompson put word out he was looking for an available driver. Bobby Unser brought
young 24 yr old Mario Andretti by the Thompson garage and Mickey immediately offered him the ride. Andretti agreed to come by the next
day and test the car but never showed. Thompson then turned to 15-time Indy 500 competitor Eddie Johnson and invited him to the team.
Johnson accepted but during his initial runs with the 82 car he was only able to get into the mid 140's.

Eddie had a great run averaging 152.905 mph and Thompson was confident it was fast enough to avoid getting bumped from the field on
Sunday and he quickly accepted the attempt. Mickey and Eddie are happy men...as are Ford execs to have a second Thompson Ford in.

Article noting that Eddie Johnson had put a second Thompson racer in the field.

Veteran racer Chuck Arnold was out of a ride after his Chevy powered MRC Special failed to make speed. After seeing Johnson qualify
Thompson's #84 car he went to the Mickey's garage to check the availability of his third racer - the #82 car. Thompson told Arnold his
team hoped to have the car ready for Bump Day on Sunday and offered Arnold a shot at qualifying. Arnold took it.

But Peter Bryant knew the crew didn't have time to prepare the #82 car for a Sunday qual run and he told Thompson as much. Mickey, under
intense pressure from Ford to get all 3 cars in the race makes the descion to "bend" the rules. He closed the garage doors and reportedly
instructs the crew to take body panels from the #82 car and place them on MacDonald's already qualified #83 racer. A risky move for sure
but Mickey figured track inspectors wouldn't be thoroughly checking the cars at this late stage. Photo The Henry Ford.

Typical Bump Day at the Brickyard, fast paced car hopping was in full swing. Drivers and car owners frantically searched each other out
in hopes of getting an available car into the field. Bobby Johns was one such driver after crashing Smokey Yunick's unique "sidecar" racer
(shown below). After hearing Chuck Arnold had walked away from the Thompson team Bobby headed straight to Mickey's garage to check
on the #82 car before the final gun on qualifying went off. But after sititng in the #82 car (actually MacDonald's #83 car) he decided "The
car just didn't feel right" and passed on the opportunity. Dave Friedman photo from the The Henry Ford Collection

With less than an hour left in qualifying Mickey Thompson went looking for of all people, Masten Gregory, who was at the Brickyard to
watch Bump Day festivities. Mickey asked him to give one last chance at qualifying the #82 car (which was really MacDonald's #83 car).
Gregory agreed to try to qualify the car but said he would not drive it in the race. Mickey had no other options and agreed. Gregory was
only able to muster a 147 mph average in the car but with several other cars in line to qualify Thompson had to accept the run. It was
ultimately good for the 34th position, the first alternate should a car not be able to run. Photo courtesy First Turn Productions.

Bump Day excitement and the joy of Eddie Johnson qualifying ended quickly for Dave MacDonald when he learned good friend Glenn
Fireball Roberts is hospitalized after a serious crash in NASCAR's World 600 on 5/24. (Glenn would succumb to his injuries on July 2nd).

He’s in and out most of the day getting much needed track time in the #83 Thompson Ford. He would twice however be forced to the pits
after body panels flew off his racer.

Some reports say that at one point during the day World Driving Champion Jimmy Clark was running his Lotus directly behind MacDonald
and after seeing unusual action from Dave's car followed him into the pits and urged him to "Get out of the car mate, just walk away". Some
have questioned this account. Jim's girlfriend at the time, Sally Stokes is on record though saying she absolutely remembers Jim telling her
he said that to Dave.

Dave MacDonald wraps up his final practice run in the Mickey Thompson 83 racer. Caption below mentions late adjustments for a full fuel
load yet that is a subject of debate. General consensus is he did not run any practice laps with a full fuel load

Jim Clark in the #82 Ford Lotus gets a great start and is already separating from the pack.

Eddie Sachs makes an early move to the outside and jumps Dave MacDonald, Johnny Rutherford and Ronnie Duman and was 13th as the
field went into turn one. In the shuffle MacDonald still looks to be in 14th position and '63 world champion Jim Clark leads the pack.

Entering the short chute between 1 and 2, Dave MacDonald still in 14th position but Rutherford would go by him before lap's end.

Deeper into one you see Dave MacDonald tucked in behind Johnny Boyd (88) with Ronnie Duman (64) directly behind. Eddie Sachs
(25) has jumped Johnny Rutherford (86) and both are in the process of surging past MacDonald and Boyd. Bobby Unser (9) with all
four below flies by Bud Tingelstad (15). David Parker photo

During laps 1 and 2 Dave MacDonald had moved past Don Branson, Len Sutton & Dick Rathman and repassed Eddie Sachs and Johnny
Rutherford in the process. As leader Jim Clark crossed the line to start lap 3 Jim Hurtibise, Walt Hansgen & Dave MacDonald were coming
out of turn four running 8-9-10. As Dave exited turn 4 and onto the front straight he pulled driver's left to make a move on Walt, and perhaps
Herk too, down the straightaway. A split second later Walt went drivers left to make his own move on Herk. Two cars behind MacDonald
was Len Sutton who would later say “Dave turned left again to avoid Walt and his car got sideways”. Dick Hensley, a fireman stationed at
Turn four said “MacDonald came through the fourth turn with two other cars. As he came off or number four he cut to pass. Then the front
end of his car lifted at least 1 to 1 ½ feet off the ground. It looked as if the wind just hit him”.

At the bottom is leader Jimmy Clark streaking into turn 1 at the beginning of lap 3 and at the top is the start of the crash that would claim
the lives of talented racers Eddie Sachs & Dave MacDonald

The aftermath. The fire truck at the very bottom of this photo is parked next to Dave MacDonald's car. The dark marks on the track show
the path Dave's car took to get there - the initial impact on the inside wall and the second impact at the outside wall. Cars making it through
have come back around to a stop as race officials halted the race. This is the first time in history the Indianapolis 500 was stopped for a
crash. Image courtesy of the William Oates-Phil Reilly Collection & Vintage Motorsport magazine.

headlines will read. Two popular racers - Eddie Sachs and Dave MacDonald would die in the fiery crash. RIP Dave and Eddie. Photo IMS

A record payout for the 1964 Indy 500 and race winner AJ Foyt's share was a staggering $153,650. The richest Formula One race in the
world at the time was the 1964 Monaco Grand Prix and race winner Graham Hill's payout was a mere $2,000. It's not hard to understand
why the best drivers in the world flocked to Indy every year.

The Thompson team was awarded $11,000 in prize money - $5,900 for Eddie Johnson and $5,100 for Dave MacDonald. Dave's portion
of $2,040 was given to Sherry by Mickey Thompson.
