PS BTW, I remember taking an El Al flight from Athens to Israel right after the bombing of the El Al office in Syntogma Square in Athens. As we boarded, they threw questions at each person so quickly and jumped around re subject matter so much, they could have caught anyone who was lying. That flight was the nicest I've ever been on (perhaps because the plane was mostly empty, LOL).
