Beech is probably capable of being rolled...... By someone who knows how. It would seem those chaps didn't, idiots! Hence it's something only a test pilot should attempt, rather than some gash line bloke merely guessing what the correct tecnique is. Line pilots should only ever do this in a sim, as part of the unusual attitude or upset training. Part of my 777 training was a recovery from inverted. However, I don't think any Boeing test pilot has ever rolled a B777?
