The fact he wreaked of chemicals from toilet would concern me greatly, is what you say possible?? Could a bomb be placed there to go offf months in advance? Don't they empty those septic tanks on plane, or could one be lodged in there and not come out??
Have you notified Northwest Airlines of that possibility if you have that kind of expertise??
I dont know if a bomb could be placed but here is my theory you tell me what you think....
1.Each guy goes to the toilet and unscrews One bolt around toilet
2. Then Guy with Mcdonalds bag goes to bathroom. Gets contents of Mcdonalds bag from stash point from catering company that is past security.... like a garbage bag in a bathroom placed by an insider custodian. Takes it right only plane.
3. Since the previous 14 guys basically unscrewed the toilet he removes the toilet, sets the bomb and spends the rest of the time rescrewing the toilet down.
4. Air marshalls search toilet can not find contents of mcdonalds bag..... because it was put directly into sewage tank
5 It is atatched to the tank somehow and does not block the drain to the outside.
6. Bomb goes Boom months ahead of time.
That is the only way to explain the fact that the air marshalls could not find anything extra in the bathroom and the guy smelled like toilet chemicals when he returned to the seat. Bet the bomb or package is still in the sewage tank of the plane.
The above is my theory nothing more.
