For anyone who is interested in the air war from 1941 to 1945, the information provided here is of inestimable value.
There are no more than a handful of Second World War Luftwaffe members alive today.
Patrick Eriksson had the foresight to record these experiences first-hand before it was too late.
Some witnesses ended up as senior fighter controllers.

By no means all the witnesses were from the ranks of the so-called 'aces'. It was on the Eastern Front that, essentially, much of the Luftwaffe was destroyed, and this is the subject of the second in the author's trilogy.
Death wasn't always in the air: '"Quick, out of the aircraft, the Russians are here." The airfield had been overrun.
Chaos followed.'In addition to giving voice to those who were there, Patrick Eriksson describes pilot training and scrutinises the Luftwaffe's complicated victory claims system to find out if it really was as accurate as is often suggested.
