I flew with Collings 10 months before the accident, I flew in 909 plus the B24/25 and Mustang. I received a fairly comprehensive briefing before each flight but then I fly and have a good grounding in aviation so to the general public it might not have been so comprehensive? The seat belts were the old buckle type which I guess could be hard to use to some. Seats in the back of the B17 & B24 were non-existent purely seating on floor backs against bulkhead or side wall with seat belts fixed to floor. Over the two days I flew I had the time of my life! After the accident Mrs 10D grounded my war bird activity! She is warming to me doing a Spitfire flight though!! I had plans in my retirement of volunteering with Collings each year as I was so impressed by the operation! I was shocked mind you to hear that 909 had been grounded the day after my flight with an engine change needed!
