Help with some old airport ID's
Hello all,
I recently acquired a TWA navigator's logbook and flight time record that covers the period 1951-1953. I've been able to decipher some of the 4 letter airport codes, but others are a mystery. The canadian and us codes are similiar enough to their present day ICAO counterparts to be recognizable. However, the european and middle east codes differ from the modern day ones enough to puzzle this colonial. Bearing in mind the route structure of Trans World Airlines at the time, can anyone offer some suggestions or confirmation for the following--
CSPT (Lisbon Portella?)
HEKL (Zurich? later HEZH?)
HEGF (Geneva? later HEGE?)
FFLB (Lyon?)
MAXN
ODJD (Jeddah?)
SVAA (Aden?)
SSFK
SVWA
EAMD (Madrid?)
DDRM (Frankfurt Rhein-Main?)
TFKF (Keflavik?)
4XLY
CSAZ (Santa Maria?)
Thanks.
