To be honest, I'm not entirely sure as most of the very old aircraft I have flown are not well detailed so it's difficult to find out when they first flew or were manufactured. The oldest I know for sure would be from a flight just a few days ago, on a British International Sikorsky S-61 which, built in 1972 (trip report here: http://www.airliners.net/discussions/trip_reports/read.main/116129
) - I had no idea the aircraft was so old!
Other likely candidates would be;
-C3339 - a NAMC YS
-11 which I flew in last year and only know that it was built sometime before 1974.
-AQE/AQB - Yakovlev Yak 40's which I flew just under a year ago, again they were old, but I don't know how old.
Any help on tracking down manufacturing dates for the above would be very much appreciated!
