not a flashpot... was at that show -- it was an M80 thrown from the upper deck that went off near Page. The show stopped, Page was wringing his hands and obviously shaken. Plant said "we seem to have a comedian in the audience" or something like that. They left right after that and were definitely pissed. That was the era when idiots used to toss firecrackers into the air all night -- there were actually announcements over the PA by the Garden prior to the show, pleading with the audience not to do this. The two shows I saw were great, but the firecrackers sucked -- we got rained on from the upper deck all night.
