That LOOKS like a CATM. The lau 7's on the Hornet are notorious for shedding stuff if not inspected between every flight (or properly preflighted for that matter).
That picture was taken before we took CATMs to sea. There is also a detent that keeps the Sidewinder from moving forward. It retracts when weapon is selected. If you land without deselecting it (some ircraft are different, but that is what bit more than a few A-7 drivers) there is nothing from keeping the Sidewinder from continuing forward. I saw my first one in 83 timeframe when Flag staff 0-6 bagged an A-7 ride. Oops, there went a brand new AIM-9L that was scarce to be had at the time.
