A rumour with a Pilot @ my firm states they were off for 14 Minutes and NOT1 Hour 40 Minutes or 1 Hour 14 Minutes!
This fitts well to the fact (ist it confirmed) that they crossed 4 countries southwest of Germany @ cruise-speed which would take approx. 20 Minutes.
I really doubt that they have been off for 1:40 Hrs without military interference until reaching Germany.
