I'm not sure that a drone can cut the fabric of a balloon.I agree, on the other hand
How would you feel, if you was in the one of those Hot Air Balloons?
Being circled by a drone...
not that safe
Tough call
I’m a rule breaker but...
I fly over crowds so who am I to judge
But even it could, balloon can land smoothly and safely.
I would feel fine, things to worry about are ON the balloon, not drones.
Even hot air ballooning is a safe sport, there are deadly accidents happened. I don't have time now to check NTSB, but I remember an accident in Texas (maybe not) where many people were killed, and was in news here in Europe.
