Either that or something like,
"Bronco 123, keep your speed up-break-Convair 321, take your minimum approach speed, you're following an OV-10 on final. You're 30 knots faster."
I bet you really have to pay attention to an out of CG condition.
That T-29 obviously was modified by Calspan to be a control configured aircraft. The company previously had modified a A-26 with computers that enabled it to be programmed to fly like just about anything; a friend of mine was killed in it in 1981 when a wing came off. I understand that the A-26 was to be replaced by a modified Learjet but I think that T-29 was modified for a different program before that.
I agree, the extra stabilizers on the wings is really odd to my eyes, and it looks like they permanently closed the left forward entrance door and added external stiffeners like a Bf109-F2?
