Am I crazy

I've just emailed an OU lecturer Derek Taylor with the whole  aerostat idea and I hope he doesn't think I'm too crazy.

On the good news front I've got a return email from Theo Botha, Head of Sales a Blade Dynamics.

I've also got a response from Siobhan Dunn from Lindstradtech.

My big worry is how much to tell them. How open should I be.
