All I can tell you about the stall characteristics of the P-38 is this. The following P-38 pilots (real pilots who flew it between 1942 and 1945) Stan Richardson Jr., Art Heiden, Ken Lloyd, Bill Capron,and several others, stated this for the record. The P-38 did not snap roll inverted nor enter a death spin unless missing parts of the flight surfaces including control surfaces, or assymetrical power was applied. Period. It may eventually spin out of a tight turn if speed drops too low (it will maintian level straight ahead flight at 75MPH), but even then, it will not exhibit the bizarre characteristics it does here in AH. All that is necessary is to get nose down for a LITTLE speed. It will recover at 10 degrees nose down and just over 100 MPH. It will NOT lock into an unrecoverable spin. It was neither necessary nor desirable to pull the throttles back or shut down the engines. You should only close the throttles or shut down the engines if one is already out.
Stan Richardson Jr. was an advanced P-38 instructor AND a combat pilot. He had as many hours in the P-38 on one engine as most pilots had in it period. He can tell you more about the flight characteristics of the P-38 than just about anyone alive today. Not only have I asked Stan any number of questions, but other pilots who flew the P-38 have told me that if Stan says it is so, you can take it as the gospel regarding the P-38. When guys like Art Heiden say that, it is fact. Don Rheimer said the same thing. Few pilots had more hours in the P-38 than Stan did. Although I do not know him, I hear the same is true of Erv Ethell, father of the late Jeff Ethell. I do know that Erv Ethell had well in excess of 3000 hours in the P-38, and was himself a combat pilot with several victories and an advanced P-38 instructor.
