There's a 'van' operating out of EN these days often (shifty business) & wonder what the ability of same would be if an eng failure occurred at say 300ft on a typical day say 10 kts H/W. Can these big lumbering ducklings turn & glide back to the rwy from that height? Some guru 'van' man (or gal) might be able to shed some light here.
As for why the '6' failed? Can only be fuel related. The other 2 things needed for an 'infernal' combustion engine to work will always be there once running unless hardware mech failure prevailed which still really means fuel not being supplied or the inability not to be able to turn.
Now I know why we have '2' of 'em, safety in numbers
