Ah, yes I knew this would be coming
I started my organization because of restrictions around those organizations - most Angel flight organizations (AFE,AFW,PALS) have stiff requirements around hours and certifications; I believe in part some of these are set between lawyers and the FAA, for good reason. By the time I meet some of those requirements, I'll have helped save well over 500 to 1000 animals from euthanasia. You don't need anything special to help save an animal.
I did join Angel Flight East, out of Blue Bell PA as a ground volunteer, and after having conversations with their director, I found that there is usually never a shortage of pilots willing to fly their patients where they need to go. Additionally, they will pay for commercial flights if for some reason a volunteer pilot cannot. In the animal rescue world, thousands of animals are put down every single day, simply because they cannot get to areas where they would be adopted.
So, I found a way to make a positive difference with my ability to fly in a different way. No good deed goes unpunished, and I've learned to have a thick skin in the non profit world, so sarcasm doesn't bother me. I've done a lot of research and have had nothing but support from my local FSDO.
This year alone I've spent over $6,000 of my own money, renting aircraft and transporting animals from kill shelters to places they will be adopted and allowed to live. The goal is to own an aircraft under the non profit, to bring my operating costs down $30 to $40 per hour from where they are now, which increases my efficiency and allows me to help save even more animals. For $80 to $90 per hour, a C182 could allow me to transport up to 30 animals 100 to 140 miles in one hour, as opposed to the maximum of about 15 I can transport now, at over $120 per hour.
There will always be critics, but I sleep OK at night doing what I do
