Sad to report that Chris Orlebar passed away this weekend. As one of the team involved in putting DG together, I met Chris when he came to Brooklands to check progress quite regularly. He was, quite simply, a really nice guy. Helpful, interesting, and above all a true Concorde enthusiast.
I recall on one occasion sitting in the cockpit with Chris a few years back when he chatted on at great length about his days on Concorde, whilst also expressing great interest in the work we were involved in.
Chris also published a book about Concorde which he updated and revised regularly. He was a true gentleman, and one of the best of the Concorde breed!
