This is about humanity. Some people have the unfortunate luck of being VERY ILL. Next time you’re in hospital you’ll find out how many very sick people there are. Having had a brush with melanoma and hearing of the regular horrendous road trips people were undertaking for treatment, I am appalled at the inability of some to make
what is possibly end of life treatment just that little bit more comfortable. Do you have no sympathy?
No it's about safety and standardisation. Calling yourself "Angel Flight" has no official bearing on anything and is non-standard. If you want a real call sign then you need to apply for one so everyone knows who you are. The last thing we need is some cock-up on the radio with call sign confusion. Murphy's law is very real in aviation and we don't need to make it any more difficult than it is. I can see it now with a Military Aircraft "angel" call sign getting mixed up with a PPL "angel flight" callsign and someone busts a cleared level or something similar.
