Whoever approved letting this nut job go back to the boarding lounge and get on the HI flight needs to be mopping bathrooms at LAX permanently at the very least.  Had he breached the cockpit door just after take off, there might not have been time to scramble jets before he was over downtown LA.  BTW, if you were on this flight, those F-22s were out there to take you out of the sky before you hit Honolulu.
