SLF query
Hi all
A friend of my parents was flying yesterday from Nice to Tel Aviv (the flight was the 12.40 ISR) and it was delayed on the ground for a couple of hours - the cabin announcement was that the delay was due to over crowded skies around part of the route (I think it was Cyprus).
I'm interested to know what could have caused that, (eg was it bad weather elsewhere that made re-routing necessary) and how common it is. I'm also interested to know (this because I've been asked by folks) why if the air conditioning on the aircraft was not being run, the cabin doors could not be opened to let some air in.
I'm assuming that the doors stay closed simply to stop people wandering around and falling out, but would be glad to know if there's any technical reason! (The more serious question is the overcrowding one).
All help gratefully received.
