Excellent info, Simon, thanks for the confirmation, Graham, and some more lovely personal memories and thoughts from David. Thanks to you all.
There now follows the first of two diversions. As far as I'm aware Tim has no particular interest in aircraft, either military or civil. but these appeared in a 35mm railway film and as I know there is more than a smattering of interest in things aerial, and as I guess I can divert my own thread if I want to
here are the photos. Tim's brother in law and sister lived in Cranford, next door and under the flight path to Heathrow, and I suspect these were taken from the back garden. From their position within the film strips I'll guess at these being about 1976 (actually, I suspect this date is more accurate than the proposed 1980s for the railway photos at Old Oak and Willesden above). There may be a clue in the "British Airways" rather than "BOAC" and "BEA" branding. I've taken a guess on the aircraft types for those I think I recognise, but confirmation of those and suggestions for those I don't recognise will be appreciated.
Firstly I believe this to be a British Airways Vickers Viscount.
Next a Boeing 747, coming and going, again of British Airways. It has the BOAC logo on the tail. Was this used initially as the logo for BA?
Another British Airways. Is this a Tri Star?
I freely admit to not knowing this one or the airline.
I don't know this one either but will take a punt at a BA Boeing 707.
Finally is this an Irish Boeing 737?
