A long time ago ...
Many, many years ago I worked for a year for a company that makes flight simulators. They had a contract to build a new simulator for the Indian army - I think it was for helicopters, but don't quote me on that. While the simulator was being built the Indian army constructed a nice new building to house the simulator.
This is where it got interesting.
The Indian army got the Indian air force to ship the simulator out in a Hercules, flying it into the army base (which had a runway) that would be the future home of the simulator. This the air force did very happily. When they arrived at the base, they taxied to the end of the runway, opened the boot and shoved the simulator (in its transport cases) out the back, then left PDQ before the screams of outrage started (note: this was in the monsoon season, so it was just a touch damp out there).
Once sanity had been restored and the simulator moved under cover, the company I worked for had to assemble the thing in its nice new building. Everything went well until the time came to mount the cab on the simulator frame, at which point they discovered that the steel covers on the cable ducts sunk into the floor where not strong enough to take the weight of the cab + huge fork-lift that was carrying it.
