I assume the Iranians were concerned that closing the airport would have
cued the Americans that there were up to something. Of course, it
appears that the American bases had plenty of time to get in the
bunkers, so closing the airport would not have changed anything in
practice. Then they also said that the flight path was over a secret
military base, and of course they had not warned anyone about the
location of that base. Little wonder that the Iranian civilians are angry...
