I asked a question the other week, and wondered afterwards if it was stupid enough to appear here:
me: Do winglets have any effect on wake vortexes?
CSD: Not really, they just push the wing tip vortexes a bit further out and reduce drag.
Talking later to one of the FA's and mentioned that I could just remember BEA flying DC3's. She asks 'What's a DC3? I've heard of a DC10, was there one before that?'
