As mentioned the airshow is the best place it seems to get this to the public.
Could even be a passive approach handing out information flyers near the CASA booth.
Of course many Angel Flight supporters could ask CASA representives all day everday about what’s happening.
The general public have no idea about this.
Use the airshow to your advantage, Australia free speech, try and get the media involved.
Not an easy task, very easy for me to type, I won’t be there. I’ve never done an Angel Flight, have had no direct involvement in anyway, I do see what is a good cause though.
I wish you good luck. Take them on in a stage where they will not want to be brought to account.
It seems like it’s just meant to be with the airshow fast approaching.
Lastly do you have past users of Angel Flight who can be there with you advocating the necessity of the service?
