U-Boats had a lot of random issues

During World War II, a German U-boat was sunk by a truck. The U-boat in question attacked a convoy in the Atlantic and then rose to see the effect. The merchant ship it sank had material strapped to its deck including a fleet of trucks, one of which was thrown in the air by the explosion, landing on the U-boat and breaking its back

LOL, sucks for them. Totally deserved it though.

Ya I can't imagine what it would be like to have my boat sunk by a truck.

Just funny if there were any survivors and they were asked how their ship sank. "Ummm we blew the shit out of that ship and just so happen to be a truck on it and it flew and crushed ours. Yeah it happened just like that too."
