How has Israel’s office airspace remained available?

.GIVEN THAT THE blood-spattered strike on Israel on Oct 7th, about 90% of airlines flighting to Israel, featuring British Airways and Emirates, have actually suspended flights to the country. Hamas, the militant group that works the Gaza Strip, has consistently discharged rockets at Ben-Gurion flight terminal, Israel’s largest, near Tel Aviv. On Oct 9th one landed nearby, sending out travellers rivaling cover.

However Israeli airports, including Ben-Gurion, remain to function. Why and also exactly how have they kept open?
