Yes, some wonderful stuff on this film, but to get the "GOOD" details in the introduction, completely ignore the first summary, and go straight to the second one, which is written by a cople of fellows who know what they are talking about. Ordering ANYBODY, and particulalry somebody who has not got a clue on the main subject of a film is a waste of time and money. They may be normal, well adjusted and probably reasonably intelligent people, but asking them to identify aircraft from another era is a HUGE ask, and frankly putting them in this situation is just so unfair. Thank goodness for Errol Martyn and the other person who were presumably asked to provide the vastly more informative second attempt at a good commentary!
