Treaders : Do you think the photo of the Junkers nose has just got the north end of the Croydon terminal building creeping in to the picture. My guess is that they were all taken at the same time, and three of them from pretty much the same point.
The flight in the DH84 Dragon could likely be one of the 5/10 minute "joyrides" that were popular there at weekends (when the number of such passengers probably surpassed those on regular flights). There were several operators based there who would get involved. As the photos were taken "airside" they may have been shot while being taken to/from the joyriding aircraft.
Leica : Oh, well done for spotting Djalak was a DC2 and not the more ubiquitous successor, the DC3. It was delivered in April 1936 so I would guess the photos were from one of the summers 1936-39, possibly one of the later years as the DC2s were initially bought for the long flights from Amsterdam to what is now Jakarta, Indonesia, and on to Sydney, but were bumped down to local European runs by KLMs later and larger DC3, which came on line from 1937 onward.
If you meet Dr Frank Anderson, from the aviation society, at Croydon tomorrow, do give him our best regards - a number posting in this thread had a meet-up there a while ago and plagued poor Dr Frank with excessively detailed questions, and then even worse answered them before he could get a word in edgeways
