We did indeed have to clear it to destination! The funny thing was, I think it may have been 1982, but Maof, with their 720s and Middle East Airlines (MEA) with their 707s were operating at the same time it wasn't unusual to see them parked next to each other!
Interesting seeing the old mayflys. Two things stick out. One was the 1-11 departure most mornings at 2 am, bet the locals loved that! Also 1980 was the start of Corfu becoming very popular, on some days there were 4 flights. I went in the August of 1980 with Monarch on a 720 and the crew were saying they spent half there time going there!
