So how is it legal or sensible to have 1 person doing 80 hours non stop. Indeed as is being shown on Uk TV at the moment it is very hard to remain awake and alert for even close to that long.
What does this say about Virgin Atlantic. "Dont worry passengers today we will be sharing the sky with one of our aeroplanes where the pilot has not been to sleep for 3 days."
IMHO this must be treated as a UAV rather than an experimental aircraft and denied access to controlled airspace. Particularly as their route is taking them straight through some of the busiest airspace in the world.
I would not want it just 3000 feet over my head when Steve F drifts off to sleep and the autopilot drops out.
