On that subject, I have wondered why there isn't a nonreligious charity providing aviation support to humanitarian work. Whilst I've nothing but respect for the work of MAF, as a non-christian I'd effectively be excluded from doing anything to help, and certainly christians have no monopoly upon either compassion or ability.
As an open question, is there a need out there for some form of "aviation sans frontiers" that could provide permanent air assets for humanitarian programmes that might benefit but would struggle to afford their own?
Just a thought, and not to denegrate the excellent work of RedR (or any other NGO) or the approach that they're currently taking.
