Time Traveller:
Beyond the call of duty for Flyglobespan to return the passengers, I would have thought. If they choose to diregard the information and reassurance of the Captain, in the process delaying all the other pax, then they should have to deal with the inconvenience of getting home themselves.
I don't know Flyglobespan, but maybe they are one of those silly companies that believe in customer service and repeat business independent of said customers' IQ levels?
