Heliservice have been working with AW169s for a while and according to heir website they have been working with REGA.
Even though they need to employ extra staff to service the AOC it appears many find it cheaper to go for their own.
It is a way of burning all the embarassing bank balances they accrue from good fund raising... it is there to look after them when a 'rainy day' comes along. It saves them even more money overall so they need to buy a bigger or better helicopter and then they need to buy a field for building on and then build a snazzy new base that saves them yet more money.... Along comes a money slowing coronavirus that might be classified as the rainy day so they plead poverty and yet more more comes in... So now what do they do with the bank balance?
