Thanks for the comments
I assume that the manufacturers/operators must be involved in putting stuff in these places.
My thought started with remembering seeing a story of a plane delayed because no towbar was available at a normal field. I think it was an A3456 (Manchester?)
The Swissair plane landed in Iqaluit and needed towing which blocked the runway. If they didnt have a towbar/truck what would have happened? Sure its all managed but was just intrigued who managed putting equipment in these remote diversion fields. As SLF I guess I should just be happy to be on the ground and hope there is still enough wine on board!
