All these posts are missing the point.
What would appear to be a filed aeromedical flight with a serious casualty on board was denied landing at the destination airport because it would arrive there ten minutes after normal closing time.
This ill-conceived action almost certainly put the patient at some risk.
The persons responsible for this casual indifference to a seriously ill pax should hang their heads in shame instead of muttering about "feeling a little tired" or offering other lame excuses.
Perhaps the flight had not been filed correctly, perhaps the inbound captain failed to pre-fix his calls with "This is an aeromedical flight" but if neither action was omitted this one looks as if it is down to Southampton's attitude towards passenger care.
