Christian, this is a wonderful book by the late Brian Calvert, in that although he goes into quite a few of the more intriguing Concorde technicalities, he does so in a manner that is easily understandable, even by me
, and gives a wonderful insight into what it was really like to fly this amazing aeroplane. I had the pleasure of working with Brian on a 1994 BBC2 Concorde documentary, my brother had the shock of his life while on holiday in Mauritius the same year, when he picked up a copy of The Times only to see Brian and I 'posing' together in a publicity photo for the programme.
The other two Concorde books that I would personally recommend are 'New Shape in the Sky', by Ken Owen and 'Supersonic Secrets' by Rob and Edwin Lewis. These two books, one old and one quite new, are absolute Concorde classics in my very humble opinion.
Best Regards
