Yes fustall, you definitely saw a Sentinel, and Dave Reid said his money was on a Ryanair 737 - how much did you lose Dave?
£1. Now I can't afford to use the loo on a Ryanair flight.
Though technically my tongue-in-cheek suggestion hasn't been proved wrong yet - we're now back on the identification made originally in post #6, so who's to say we're not going to go round the loop again?
