I would like to contact Mark Lane who is listed as Walter Tydon grandson in the P-40Q reference. If possible could you please forward my information.

We are trying to obtain a photograph to put in our aviation Hall of Fame.

Thank you,

Re: Mark Lane entry regarding an assocaition in design between the P-40 and P-51 Mustang. The development of the Mustang fighter was completely independent from that of the Curtiss P-40 or the XP-46. The study which fathered the Mustang began as a work commissioned by James H. Kindelberger of Dr. Clark B. Millikan at Cal Tech (G.A.L.C.I.T.) in March of 1938. Having any Curtiss data on hand at the time the Mustang (X73)prototype was under construction in 1940 was a contract requirment by the British to assist in the conversion to P-40 production had the Mustang design failed. The document package purchased was not used in the design or construction of the Mustang due to aerodynamical, structural and systems differences.The P-40, according to AAF records, was never intended to be a production aircraft, since its primary use was to test the liquid cooled engine, Allison V-1710, for use in tactical aircraft. Unfortunately, errors in assumption by some noted aviation historians has been taken as gospel on this subject.

The second XP-40Q was the only one to survive the scrap heap and was sold to a Joe Zeigler for a few hundred dollars. It was given the civil registration NX300B and was planed to compete in air races with the number 82. It was an unauthorized starter in the Thompson Trophy race of 1947, where it was running in forth place when the engine caught fire and the pilot bailed out, consequently the aircraft crashed and exploded.

My Grandfather Walter Tydon who designed the P-40 wrote a
book that I wish to publish. Hum, why is it that the P-40Q looks a lot like the Mustang or is it why does the Mustang look a lot like the P-40Q. Is the Mustang actually the
XP-40 and the XP-40Q combined ?

In 1945,an XP-40Q was lost in a fatal crash during flight tests at Buffalo,New York.While doing slow rool tests at high altitude,the XP-40Q went out of control and crashed.

Just curious, any of those (only two?) XP-40Q's survive?! If so, where would they (it) reside...private owner or public display somewhere? Sure does look a bit "Mustangy" doesn't it, with the canopy and the four blade prop!
FYI, Recent communication with Jeff Greene, Ex. Dir. of SAAHF mentioned that recovery efforts will begin again in mid to late August, 2005 of AVG (Flying Tiger) John Blackburn's P-40E from Lake Dianchi, China! He also states that no major(U.S.)corporate sponsor has been secured yet...PLEASE pass the word!!! Thanks!

The XP-40Q Was elvulated by the USAAF But the end of the war led to cancellation of development of the Warhawk and the second XP-40Q prototype ended its carrer as a postwar air racer.

On October 1945,a Curtiss XP-40Q suffered an engine failure during a test flight near Muroc,California and belly landed in a sweet patato field.The pilot was not injured.

For those of you who are scale modelers, Amtech is coming out with a 1/48 scale plastic model of the P-40Q sometime soon in 2004.

XP-40Q Max Speed was 422 mph at 20,500 ft.
Service Ceiling was 39,000 ft.

What a difference the V-1710-121 with two-stage superchargers made! Along with the many refinements of the airframe.
