Once again thank you all for the answers and your time. The flight planning was completed, but the student did several things which jeopardized that. He verbally confirmed with me that he had called and received a weather briefing, but calling the briefer revealed that he actually didn't. He did file a flight plan, but never opened it. I had instructed him (again verbally) to get flight following for both legs of the trip, which he did not. The more investigating I do into this the more I find he lied to me and largely ignored my instruction. The student is a Chinese national who is here receiving training on an airline contract. He had a private certificate issued in china, and his attitude towards primary training hasn't been good. Also, another student had done that same cross country earlier that day. That student (who I also endorsed) had completed the trip successfully. The two students are friends, and I think they might have used the same flight plan and I didn't catch it. All this is just my word though, and I'm very worried. The incident occurred on 5/26 and I haven't even received a phone call yet, but it is the holiday weekend. Anyone know what the time line on this kind of thing might be? Any help on this would be appreciated
