The AFM for the Metro calls for the props to be feathered prior to a wheels up landing with all wheels retracted. Wasn't sure if that happened or not last night, but the photo confirms the feathering, therefore the crew would have had a handful landing and shutting down both engines. Single pilot ops would have made it harder - good two were on board, even if one was under training.
No gear, no flaps and no prop drag - would have been a decent float, definitely would have taken the longer runway myself as well. Wonder if there were any problems opening the cabin door? Hope the crash axe was ready!
