It’s Intrepid, not “Entrepid”.
Sorry, my fault, I started it !
Waiting for my family to join me before we bought the tickets to the "Intrepid", I mentioned that although I never flew Concord I was still a retired B.A. pilot, and how about a visit to the Concord ? ( not then knowing the entry fees ) I was told that as an ex-B.A. crew member I was entitled to a free ticket for myself and one other, so self and son entered free, and we just bought junior tickets for the grandchildren ! Won one, but unfortunately the Concorde was unavailable that day. Will try again next visit !
