Today's question comes from Mark L. He asks, "I am always curious whenever I see that credit card commercial with the dramatization of the guy that bought a weather balloon with points (yes he did!) what's up with that? Can anyone just buy a weather balloon and launch it? Aren't there air traffic and safety concerns? This guy and his friends seem to be sending the thing up in a somewhat remote area, but are there FAA or other regulations that control who can launch balloons like this, and where?"
