Most probably Tempelhof in 1936. ALIX was the second He 111 to fly, before the V2, D-ALES. It was originally designated as a He 111c (lower case). In March 1937 this aircraft crashed in Bathurst, Gambia, arriving with mail for South America which was to be transferred to a Dornier Wal. The Ju 52 D-ASIH crashed in the French Alps on 3 December 1936. Behind that is Hitler's personal Ju 52, D-2600. Until April 1936 this was c/n 4021. It was replaced by c/n 4053, also D-2600.
