Training Frame
Maybe it’s been thought of, but in terms of tying up a frame for training, would it not make sense (and in that case is probably a stupid idea) to go out and pick up a used 737-700, and use that for crew training for currency trips and base training for the Poseidon and the E7, you could also put it in a 50 seat all VIP fit and use it for shorthaul VIP trips when not engaged in training
