Imagine waking at dawn, face Mecca and start fast. Pilot the 747 with another hungry jock at noon for an 13 hour flight West to London. The Sun shines, no food, no water for already 20 hours, arriving into London's congested terminal area at evening peak. Blood sugar is low, body's dehydrated. Never mind the poor 400 paxs and blighters on the ground. At least we'll both go to haven!
