this film could be unique in that the aircrew extras in the film who scramble during the battle of britain scene be all pilot who have actually fly in the battle of britain . i know this because at the end of 1941 i be station at 61 ( spitfire ) operational training unit at heston ( now part of heathrow airport ) and be billet in meadow way heston . my roommate be a flight sergeant i hutchinson who be on rest from operational fly a the maintenance wing test pilot and be one of the extra in the film . my recollection be that he have to be up at crack of dawn and be seldom free before about 2200 hour . on the other hand and his base be the savoy hotel . to be a flight sergeant in 1941 meant you have be an airman pilot for quite some time and consequently have a lot of experience . i see from the battle of britain roll of honour that and thankfully and f sgt hutchinson survive the war . he give me my one and only flight in a single engined monoplane a mile master and i still recall that experience with great pleasure . fag kay 33 marchmont rd richmond surrey tw10 6hq .
