I don't think it's the pilots who get planes banned. It is the whiny earth-dwellers who complain about it to local news stations and create a huge hype about a non-event.
Yes, there are regulations to keep aviation safe but nothing jumps out of the video like endangerment of human life. For all we know, the water past the bridge might be dangerous - filled with stumps and/or ferries crossing the river.
Float planes on water? Sightseeing helicopters touring landmarks? Airplanes at airshows? Let's ban them all!
Don't forget, there is no greater power in the world than miffed soccer moms with agenda and nothing better to do.
