(AGI) Rome, Sept 14 - A Middle East Airlines plane that was escorted to Fiumicino airport by two Italian Air Force jets on Sunday took off once again after bomb disposal experts found nothing on board. The ME214 flight from Geneva to Beirut had requested assistance for "problems on board", most likely suspicious luggage. The two Eurofighter jets from the Italian Air Force base in Grosseto broke the sound barrier at a relatively low altitude while on the way, causing sonic booms to echo north of Rome. . .
