Hehe, I had the pleasure of flying one of the old Olympic 727s out to Rhodes, I think, back in the late 90's. It wasn't QUITE like that but I can see how the humour would hit home with people who flew Greek airlines in the even earlier days than that.
It also reminds me of being on a local bus in the mid 80's and being handed a chicken to hold (in a box luckily) by an old lady. There were no goats on that bus but it smelt like there maybe had been in the recent past. I really do miss those days. Even the local buses are now super modern air-conditioned boxes where the driver will rant at you if you so much as open a bottle of water! Since many Greek men (or women) over the age of 30 are yet to discover the joys of deodorant, I would prefer hanging out of an open window with a chicken on my lap every time.
EDIT: Watching again, that does actually look like it was filmed inside a 727. I wonder if they used SX-CBA which is apparently "preserved" at Hellinikon?
