If this is the incident I think it is, one of the pilots concerned later survived a second mid-air collision when he was attacked from behind and above by a light fixed wing aircraft. A lucky chap (or an unlucky chap, depending on your viewpoint)!
Sav, I do actually have have a scarf (a nice yellow one with little tigers' heads on it) I but have never routinely worn it in civvy street because I'd feel a complete "plonker"!
