One thing is fairly certain.
If CAsA try and regulate it, the cost burden will make the whole Angel Flight concept untenable.
CAsA are simply incapable of writing regulations that work. A very cynical old man once told me that was in the bureaucrats handbook. Never write rules that work because then they would not need to employ more people to amend them, or employ more lawyers to interpret them.
Look no further than the rest of the aviation industry, and in particular GA to see the result of unfettered bureaucracy in action.
They have promoted themselves very cleverly as the Champions of "Joe public", manipulated the "mystic" of safety to such an extent that the average punter and the politicians are convinced, anyone involved in aviation is a homicidal lunatic hell bent on wiping out the entire population.
Can anyone remember when CAsA had anything "Positive" to say about Aviation?
I sure cant, nothing but negatives, with them in shining armour protecting Joe Public from us.
Angel Flight in the USA is huge, by comparison, our operation is insignificant.
The FAA was wise enough to let it alone, because they realised the alternative was people taking to the road.
CAsA would take the view that people dying on the road was a good thing because it would not reflect on them.
