Just watched it all the way through-superb! Especially as I transited LHR/Thiefrow in 1964, aged 6, flying in on a BEA Vanguard from Manchester, then on to Biarritz via Bourdeaux, on a BEA Viscount. I remember parts of it pretty clearly and the return journey. Later, from 1971-5, I was a spotter, mainly in M/C, but with occasional-wonderful-visits to LHR.
