Have the NTSB confirmed anything about the aircraft configuration--engines operating, gear, flaps during the entire traffic pattern? I've wondered how often the pilots of old warbirds do any simulated engine failure training, which (most of us know) would need to be done Far above traffic pattern/circuit altitude.
They will probably take months before saying anything, waiting for the full investigation's results.
It's so nice to be retired from the career! I only miss the hand-flying up to FL 200 or the many hand-flown approaches and landings. Retired on the B-717 (MD--).
