Lebanese Transport and Public Works Minister Ali Hamie published an email on Twitter, dated Jan. 15, covering a technical assessment of damage found below the cockpit. "After close examination, it was determined that it was not the result of a bullet," the email said.
?egean said it had notified Greek authorities and Beirut airport authorities and expected to give an update on resuming flights to Beirut in the coming weeks.
