And what's so different about 5 tonne aeroplanes? Flown plenty of 0.5 tonne aeroplanes and flown 400 tonne aeroplanes, all do pretty much the same thing. If some cowboy drops in in front of you, the 0.5 tonne aeroplane has 0.5 tonne + a little bit of lift and the 400 tonne aeroplane has 400 tonne + a little bit of lift. Use the appropriate amount of lift and get out of the way! Can't be that hard surely.
