I guess thses guys were gaming the game?
On May 4, 1940, a Bf.109E (Wn: 1304) was flown to RAF Boscombe Down, where it was appraised by the Aircraft and Armament Experimental Establishment (A & AEE); then later flown to the Royal Aircraft Establishment (RAE) at Farnborough for handling trials, and allocated the serial number AE479. The results of the RAE's evaluation were discussed on Thursday, March 9, 1944 at a meeting of the Royal Aeronautical Society in London, at which M.B. Morgan and R. Smelt of the RAE lectured on 'The aerodynamic features of German aircraft'. About the Bf.109E they had this to say:
Safety in the Dive
During a dive at 400 mph all three controls were in turn displaced slightly and released. No vibration, flutter or shaking developed. If the elevator is trimmed for level flight at full throttle, a large push is needed to hold in the dive, and there is a temptation to trim in. If, in fact, the airplane is trimmed into the dive, recovery is difficult unless the trimmer is pulled back owing to the excessive heaviness of the elevator.
[EDIT] I guess I could have pointed out that in the game, if you have combat trim turned on, it will automatically trim into the dive which is what the pilots above caution against, so if you don't trim out manually you will dive into the dirt like a lawn dart.
