Just two of many memorable fam flights. JFK-LHR on the J/S of Concorde including the 31L Canarsie departure - and no jetlag after an eastbound oceanic flight, and, in 1970, taking the L/H seat 5mins after take-off until TOD on a PMI-MAN Dan-Air Comet, navigating (i.e. setting up the VORs NDBs etc) and doing the R/T.
On the subject of third parties flying the a/c, I remember in the late sixties a Cambrian Airways Viscount Captain who regularly took his 16 year old son along and allowed him to fly the entire trip including the take-off and landing. This was on the night time LPL-BFS newspaper flights. I, as the only pax, was once allowed to fly an Air Anglia PA-31 for about 25 mins, some of it IMC
Unfortunately today there are too many sad people like Hew Jampton in the aviation world
The good days are over
P.S. I recently heard from a top neddy at BA that Fam Flights are to be reintroduced in the not too distant future but probably not to US destinations.
