I remember flying back from Naples to Gatwick aboard a Dan-Air Comet 4c in October 1975. We had flown out on a Boeing 727 (entering via the back door steps). I was only 15 at the time and the only other aircraft I'd flown in before was DC3 at a Hucknall air display and found the Comet luxurious with it's blue leather seating and no noticeable engine noise in the cruise, I think we all agreed it was superior to the 727 (we were but kids).
It inspired me enough to do a PPL eventually via a K13 glider a Beagle Pup and a Cessna 150.
I would still love to have a go in a VC10 which was my childhood favourite. They still keep flyng over my house on their occasional visits to Waddington.
