Hi David,
You should get hold of a copy of my book A Separate Little War which relates to his time when at Banff - September 44 to May/June 1945.
You can also get info of Flight Magazines Archive relating to him.
Sadly the family (Aitken and Beaverbrook) know longer have his material lost in a house move !!! He took some excellent film footage whilst at Banff according to those on the base, but again these have been lost.
Sholto Douglas book "Years of Command" also has info on him.
BBC Caversham, Berkshire has sound recording of him in the early years,
also Graham Warners Book on the Blenheim has a few mentions on Aitken.
The new version of A Separate Little War has new material in if my editor dosen't edit out. Let me know what you want of 18 years worth of stuff collected.
