OK, joking aside - why would anyone who is serious about promoting their profession - turn to a rumour gossip speculative forum?
Surely to goodness you would DYOR and speak to someone who is already in that position of running an air ambulance, no?
You would visit and take notes, hold meetings, speak to SME's, speak to sponsors.
In short, you'd need £5-6 million to set up a day VFR operation and require £2-3 million in donations annually to sustain it. PLUS a handful of experts in: aviation, business, insurance and law to make sure you don't come a cropper.
The good news is that this sliver of the helicopter industry attracts and commands wholehearted support from the public with their blind faith in humanity.
Value for money - it is a failed model, both practically and financially. But it tugs at the heart strings.
Good luck in your wild endeavours young sir - youre going to need it!
