Expunged doesn't always mean expunged. One of our professors here had a classmate apply at xjet and didn't report an underage drinking ticket that he got out in Bismarck because it was "expunged." Well turns out it was expunged to all agencies except the FBI, he later came to find out that xjet has the FBI do their background checks. He called HR and told them about the incident and they flew him down to Houston and ripped him a new ********* then still gave him the job. If you get the FBI to do your check and give you a copy and it comes up clean you are probably ok, otherwise just report it. Nothing could be worse than getting pulled out of groundschool and confronted about it then fired because that will follow you for a long time.
