He walked away...end of.
What utter bollox! He'd have had to do something very stupid indeed to end up not walking away.
That would have been merely an appalling landing had it not been an emergency, but not a lot worse than one sees from Cherokee drivers at any GA airfield any weekend you choose (3-point un-held-off high speed plonk-on). He seemed to have a fair old handful of power on as well! Even after he'd stopped!
But I'd have thought the missing wheel might have concentrated the mind enough to at least hold off properly. With the power right back.
Or maybe he was never taught to.....?
Perhaps at those low hours aileron to hold the wing up might have been too big an ask.
