“I fly all the time and this really is not all that unusual, even shortly after take off, once reaching cruise altitude.”
What happens when a plane reaches cruising altitude? The fasten seatbelt sign comes off and every one relaxes and/or gets up to take a wizz. Perfect time for a Pilot to do the same. Doesn’t mean anything, but attentive Pilotcide death wishers know this and Muzzies wanting to rush the cockpit adoor when it opens as well. In this case If a flight attendant did not come into the cockpit as is required in the USA to relive the Pilot that left to wizz, it had to be Pilotcide.
I heard on a tv talk show that in the United States, a cockpit must have at least two persons in it at all times.
For instance, if a pilot leaves, a stewardess must take his place so that there are always two persons in the cockpit at all times.
But the tv person wasn't sure what the law in Europe was concerning two persons in the cockpit at all times.
