Steinhilper's account of the Luftwaffe's development before the war and up to the Battle of Britain is a rare insight into the Geman side of the story. Very few Luftwaffe pilots who flew during the Battle of Britain lived to the end of the war, so the fact that Steinhilper was shot down and captured probably saved his lived and meant we now have this unique account. He's scathing about people like Galland and makes it clear that the Luftwaffe was not the mighty machine it was presented as by German propaganda. Instead a lot of bluff covered up its organisational problems, the conservatism of people like Galland (who was utterly opposed to radios in aircraft) and the obsolescence of many of their machines. Overall a fascinating corrective which is well written and which has no real equivalent.
