re: #17 lawhawk
Egypt has added helicopters and other personnel to its Sinai forces after consultation with Israel as per Camp David Accords requirements.
The Eilat airport is operating for North-outbound flights away from Sinai.
Speculation on my part:
This seems to indicate a concern/threat from SAMs.
If this had been a threat of a direct attack on the airport by say mortars/surface to surface missiles, or a direct terror attack, they’d likely close the airport entirely. I think this is due to the possibility that one of the Sinai terror cells is believed to have access to SAMs.

More support of this speculation - Arutz Sheva indicated that beginning in April, planes flying in/out of Eilat would be equipped with anti-missile systems to deal with MANPAD systems.
