The A319 operating BA967 from HAM to LHR last night was missing its starboard winglet: the end of the wing appeared to be neatly capped off in 320-100 style.
Is there a 'bus expert out there that can advise as to what the performance implications are of such an asymmetric condition (apart from making lefthand turns marginally easier, that is!)?
Presumably these things have to be removed occasionally for damage repair, rather than just dropping off wholesale.....
