From the Manufacturer:
Jack Woolams was born in 1917 and after completing university he joined Bell Aircraft in 1941. It wasn’t
long before he was transferred from the test flight division to the experimental research division. In the
following year Jack became the first person to fly a fighter aircraft coast to coast over the USA without
stopping. In 1943 he set a new altitude record of 47,600 feet and in 1944 became chief test pilot for
Bell. Another first for Woolams was piloting the X-1.
With WWII over the USAAF scrapped most of the Airacobras but a few managed to elude the scrap
yard and were sold as surplus. Some of the survivors found their way to the unlimited racing circuit.
Being Bell test pilots, three of them including Jack Woolams, purchased the two aircraft for $1.00 each
plus spares, hangar space and technical support. The two aircraft were P-39Q-10s 42-20733
(NX92847) and 42-20869 (NX92848) or better known on the racing circuit as “Cobra I” and “Cobra II”
respectively. The three prepared these planes for the big Thompson Trophy Race to be held in
Cleveland, Ohio on 1946 Labor Day weekend. On Thursday August 29 Woolams “Cobra I” qualified for
the race at 392.7 mph but he wasn’t pleased with sound of the engine. He flew the plane to Niagara
Falls, NY and changed the engine but tragedy struck on Friday August 30 when Woolams and “Cobra I”
were lost over Lake Ontario during a practice flight. Guesses are there was a windshield collapsed or a
rear structural failure.
Knowing Woolams would have wanted “Cobra II” to complete the race, pilot Tex Johnston flew and won
the Thompson Trophy beating out the favored P-51s and other P-39s. Johnston flew at an average
speed of 373 mph over the 300-mile course. On August 10, 1968, while practicing for an attempt at the
world piston-engine speed record, the heavily modified “Cobra II” was lost in a fiery crash killing the pilot.
These ex-military P-39s were stripped of everything that wasn’t absolutely necessary to fly. Over 1,000
pounds of parts and equipment were removed and 800 pounds were replaced with racing
modifications. The changes included huge belly mounted oil coolers, increased fuel, oil storage and anti-
detonate injection fluid that would make it possible to maintain military emergency power throughout the
race at speeds as high as 420 mph. To provide all this power the stock 1,200 hp engines were
replaced with Allison V-1710-135 (G4) engines removed from P-63s that put out 2,000 hp and had to
spin an 11’ 7” four-bladed paddle propeller with an extra long Pitot tube sticking out the end. The huge
prop made it necessary for the nose gear oleo to be pumped up to provide tip clearance. All flaps were
sealed and all control surfaces were skinned in aluminum. All this required the inlet for the engine-driven
supercharger to be enlarged and extended forward slightly over the rear of the canopy to reduce
turbulence in the inlet airflow.
