Hey, if you gotta burn off fuel, you may as well continue onto your destination then attempt an emergency landing there. At least that way if you survive, then you’re where you wanted to be.
Yeah, but.....
Their destination is what? 8 hours away? I would NOT want to spend the next 8 hours wondering if I was gonna die while attempting to land.
One hour (dumping fuel) is bad enough.
Except if they need medical care, the National Health System in the UK might kill them.
