Crab.....please.....can we stick to relevant issues here.
I have been called out in rat **** weather in the dark to deliver newspapers and a copying machine to a North Sea Oil Rig.....it doesn't't matter why you get dispatched if the flight falls within the Law, Rules, Regulations, SOP's, etc.
You get called....you check weather, notams, pre-flight, and go carry out your flight.
In the USA...we can file a flight plan in the air or by telephone....even those cellular or satellite kinds of talking bones.
US Customs needs a one hour notification at AOE airports.
The Bahamas may have a requirement for IFR clearances at night....but we do have to remember it is the Bahamas and not the UK.
Can we stick to the aviation part of this tragedy and not wander off down the rabbit hole you seem focused upon now?
