That's pretty funny actually 
Almost as funny as the guy who didn't bother to charge his RX battery and then buzzed over my head while I was doing my own pre-flight checks. His plane glitched and went in full power straight down about 30 ft in front of me, and he tried to say it was my fault. I showed him my 3 month old Airtronics inspection certificate and tried to be sympathetic, but I sure wasn't going to take the heat.
Er... my point is that yea it sounds like you found a perfect storm for 2.4ghz abuse by some systems not being held to TX power restrictions.
We had glitching problems with the old style radios when flying over the USAF Academy parade ground if it was too soon after heavy rain, and we theorized that it was because they used a grid of metal pipes for the sprinklers and when wet the whole field turned into a really noisy amp for our radios. We were ok if we only used 1 or 2 radios but it seemed like a third radio of any type on any freq would cause glitching.

On saturating the 2.4 GHz band, Spektrum did it for their DSMX testing.
