A short true story

Hi everybody!
Hope you are doing good well, and there here is my first topic. I'm learning English, and want to reach an advanced level.
I didn't wrtie something about myself, because it's a banal thing I think, so this is a short true story which had happened with my friend once. (This sentence is phrased a bit strangely. You could say, this is a short true story that happened to my friend once.")


My favorite illegal thing in on a plane is a petrol-powered saw. No, I didn't try to bring it, but my co-worker did.

Several years ago he had went/moved/had gone/etc to back to Russia from LV. He bought a petrol-powered saw at a Sears. Don't ask me why he didn't buy it in Vlad. I don't know still. (This sentence is correct, but it makes more sense to say "I still don't know.")

Then he came to O'Hare Airport to see whether or not he can put it in a with his baggage or not. (You could also say, "in his luggage")

Of course not. There are (You must say "were" in this case, because the story takes place in the past- even if the signs ARE still there.)

several big colorful pictures at the KoreanAir desk about it, but he said "ha-ha!" and went away with smile on face. The next morning he came to check-in with two cases. He just took a parts apart the saw and put in different cases. Didn't work. The saw was completely removed. No more smiles during the flight.

You are welcome to post your comments and corrections about it :)
