non-fictionGeneral & technical history of Hawker aircraft since 1920, circa 1961hawker aircraft since 1920, technical & historical references, notes on individual aircraft

This collection appears to be personal notes relating to Kevin Kerle's planespotting and interest in aviation in the 1960s. This includes information about individual RAAF, FAA and civilian aircraft that are involved in crashes or incidents, change their paint scheme or registration, are transferred between squadrons, are purchased, etc. Unfortunately, there is almost no organised system to them and most aircraft are identified only by registration or serial number
