I think it would be tough to jump out of a hot air balloon since the walls are pretty high and you would start acting suspciiously and then the person fly8ing the balloon would likely tackle you if you tried to get out, then you would go to jail, I'm pretty sure this would be some kind of a crime. The operators of this business know this is a risk that could ruin their business, so I am sure they keep and eye out for anyone acting strangely. It woudl be difficult to act normal just before you jump, just before ctb a person would likely look very sad and probably start to cry, I don't think you could get yourself to jumjp if you wer5e in a happy state of mind. This is a terrible idea for ctb, m ainly because it involves other people who are not consenting to this situation- it would be a very, very selfish way to ctb, since if it di work you would really hurt their business. Please do not try this.
