Think back to Christmas day a couple of years back when a 172 hit power-lines through his own stupidity and the pilot subsequently died in the post impact crash and burn.
A local charity had recently raffled a flight with the crash pilot. Makes you wonder if the whole charity thing is a good idea.
For what a basic joy flight in a 172 costs with a reputable operator versus the income from the raffle or auction, why would you bother with the hassle?
You would be better off approaching a reputable charter operator or flying school and asking for mates rates, or even better asking if they would donate the flight.
So let me clarify.
1. 'Christmas present' pilots die in power lines because they are stupid.
2. No pilot who has ever filed a Safety occurrence report should ever be allowed to help people.
3. Charities holding raffles are bad unless you [designated leftist] approve.
4. Given that you could have dinner in a 5-star hotel, why would you bother with the hassle of someone so arrogant?
5. Would you be better off doing what you essentially originally asked for [but I selfishly diverted you off on]
