Rut Roh, I don't think the FCC would approve.

Is the flight control computer going to suddenly turn the blimp upside down when interfered with?

Noooo. The FCC bans cell phone use from aircraft, even from hot air balloons, because the cell phone system relies on a network of cells that re-use frequencies. When you're up in an aircraft, you can radiate to many towers at the same time, interfering with calls.

The system was designed to be used at ground level, with cell phone towers usually about 150' in the air, so that at most a cell phone could only 'see' towers within a couple of miles. Raising the cell phone to 5,000' means you can see cell phone towers tens of miles away.

Usually it doesn't matter, and it's done all the time. (The heroes of Flight 93 on 9/11 used cell phones to call loved ones and that is how they found out the fate of the other hijacked aircraft.)

Still, it's illegal to do so, and I wouldn't be admitting to doing it in print.

Yeah, but it's gonna take about 20 minutes.
