The most surrealistic Storno episode in my experience was on a Harrier deployment in RAFG in the mid 70's, when due to a freak sky wave we had about 20 minutes sharing frequency with New York taxicabs.
Ah yes, the fun of sporadic 'E' and a MUF at VHF!!
Didn't something similar happen in the Malvinas when Icom 2m sets picked up taxi drivers somewhere in South America?
Our school CCF '88 sets' had but 2 frequencies* in the low 40 MHz range. One summer a field day was rather ruined by continuous Spanish TV on one of the channels - so everyone used the other with predictably chaotic results!
They had 2 others, but it had been found that Channel B was on the same channel as 405-line BBC TV from Crystal Palace. The locals complained, so the Army solution was a large rivet inserted through the selector, physically preventing selection of Chan A or B!
