As far as I am aware, LTN had never had a DC-8 visit when the first 707 diverted in on 25/1/70. Possibly a lack of suitable ground equipment may have been one reason, plus it wasn't until 1970, when the big airlines began replacing their 707's and DC-8's with 747's, that smaller carriers began to snap up second-hand examples of what had previously mainly been the preserve of the long-haul scheduled carriers.
So when the spotter rumour spread that there were 3 DC-8's planned into LTN on 8/4/70 carrying Ajax supporters to see their team play Arsenal I took it with a pinch of salt. The rumour proved inaccurate, because there were actually FIVE DC-8's in total on the day; 4 of them KLM, including a -63 series, plus one from Martinair. Add a selection of DC-9's from KLM and Martinair, a Martinair Fokker 28 and a Transavia Caravelle and it made for an interesting day. My pictures were all rubbish but here's a newspaper cutting.
PH-DNA 8/4/70. DC-8-63 PH-DEF is hiding behind it. Taken with a Kodak Instamatic camera having forgotten to get a new memory card for the digital one....
