Thinking of taking the trouble and strife on a hot air balloon flight and I have the lucky option of 2 sites, west and east of our house in East Sussex. I would like to pick the right site so we get blown over our house and not away from it!
Is this one operator with the option of departing from two different sites, or is this two operators, each with their own site?
What you also need to consider is the wider area around your house. If it's a built-up area for miles around, with not many places to land a balloon, I doubt whether a balloon operator will choose his departure site so that he gets blown over that area.
A quick google search showed an operator mentioning 6 mph as surface wind limit, and with a flight duration of approximately one hour, that will get you maybe 10 miles away from base at most. How far are these sites from your home anyway?
Personally I would talk to the operator, but not make too much a deal out of it. Part of the fun of ballooning, to me, seems to be that you don't know exactly where you're going to end up.
And if I wanted to take pictures of my house, I'd rent a plane. Or better yet, a helicopter.
