Regarding the book 'Ace The Technical Pilots Interview' by Gary V. Bristow, it is useful to get your head around all the concepts again (all those things you once knew) but I must say that I was very disappointed by the amount of inaccuracies and plain errors I found in the book. Another proof read (by experts) would perhaps have been a good idea. I also found the writing style a bit tedious, but that is a personal thing, I suppose.
