I was manning a booth at a trade show when a competitor launched a few

to neutral bouancy before release so they would wander the hall at constant
altitude - hopefully eye level .

Unfortunately, most of them wound up blocking air return grates overheating
the event center's AC system. I understand that was an expensive show for
the vendor.

Looks like maybe he should have gone with the RC models and had as an
attraction at his booth that you got to take the controls. Add to that
a battery powered RF video camera on the RC blimps, with the monitors
at the booth, and you'd be sure to draw a crowd.
