Last night, whilst listening in to London West ATC on 132.95, I heard Ascot 1795 calling in and being instructed to contact Culdrose Approach (HMS Seahawk - RNAS Culdrose nr. Helston, Cornwall) on 134.050, after several turns and reduction in height, handed over to Talkdown on 293.825 and followed the talkdown from 15 miles out. A fascinating few minutes followed listening to the Wren (I assume) ATC who gave descriptions, course corrections and literally talked the pilot down, quite incredible to hear, then "Welcome to Culdrose" and the pilot thanking the lady for a superb talkdown. Landed at 2222z or 2322 Local. Question is, does anyone have any idea who or what Ascot 1795 could have been - I'd ring Culdrose, but know from previous experience, that's not a very good idea in these security conscious days. My guess would be a passenger aircraft returning some crew for leave, from either the Mediterranean or Afghanistan areas.
