If they have been let go, then you're right. I sure as hell hope not.
Note to others. You don't need to fight to take over the plane. If I had half of the 14 men bring, say 1/3rd of a liter of ammonia each, and the other half bring 1/3 of a liter each of chlorine (say, all in their shaving kits), I could make a WMD that would kill every one on board such a closed-air system that a pressurized cabin of an airplane is. And the 14 men could have gas masks, or parts to make gas masks in their carry-ons.
Do not forget that they are suicidal. Survival of the infiltration team is generally Not Applicable / "N/A" to them. The recent Spain incident is a departure from the suicidal pattern however. Yes, they are just plain nuts.
