There's no bleeping way. I fly Manchester to Belfast Int. regularly, a shorter flight than London to Glasgow, but even then the times wouldn't really add up.
So you get up at 3am. Leave the house when, half 3? Travel to the airport, so get there when, maybe 4am (generous estimates here). Flight is presumably then around 6am. An hour and 20-30 minutes in the air, so we're at 7.30am and he's still on the plane. Then the plane does what it does (the last flight I got was taxiing from the runway to the terminal for 15 minutes then it took a bus ten minutes to get me to the actual door), then you have to get out of the airport and to work, it's rush hour by this point, so even if you're only going a few miles that takes time. You'd be lucky to get to work for 9. But you need to be back at the airport for 2pm if you're flying at 4pm.
Does anybody who believes this tit actually inhabit the real world?
