Some of those pumpkin cannons use high pressure air. A tank could have blown up or something.

Use of combustion is not allowed -- i.e. they can't use a cannon with gunpowder.

However, certain classes use compressed air. If a tank ruptured, flying debris could seriously injure people nearby.

Some of the classes use centripetal force, and a spinning mechanical device could fly apart.

Finally, there are classes that use stretched bands (ropes, etc.). A failure in a stretched material could cause serious injury.

I’ve seen some close up photos during the incident. It looks to me as if the pumpkin was jammed in the barrel & it was a forced chamber explosion. All that air volume & pressure had to go some where & it found the weakest point in the breech.
