Airbus A400M (Luftwaffe) on display

Recent visits by this ground-breaking military transport plane to BHX have provided some quite unusual sights and sounds that probably not many people have experienced.

As can be seen here, the props on each wing are counter-rotating, creating some interesting prop-vortex “interference” effects over the wings.
