To make a long story short, I had a friend who ordered a soviet Mig 15 jet from the federation of mother russia. The russian government ended up shipping the jet via crate on a ship into Los Angeles. However, when we ( my friend, my self, customs/TSO ) went to inspect the jet we noticed that we had 2 crates for inspection. We opened the first crate, there the jet was. So we were all curious what the second shipment was? Maybe extra parts, turbine, oil, fuel tanks... Upon opening the 2nd crate we noticed 2 23mm cannons and 137 mm cannon fitted for the fueslage. Apparently, the Russians accidentally had 2 jets mixed since my friend had specifically ordered a jet trainer. Overall it spend about 2 years in the port. He flew the jet over santa monica from time to time. Ended up spending $200,000 in noise fines ( low level cruise flights ). He sold it about 4 years ago to a museum. True story.
