You can watch this on Hidive, but it's also on YouTube:
When they get ahead, the M-66 triggers a partial collapse of the building to get at them.
Scrabbling away, throwing whatever they can get to slow it down, they are left on a slim outcrop.
A mistriggered explosive goes off at the wrong time and the M-66 falls off the building.
Just before the floor collapses, they are scooped up by an Army helicopter.
The military recover the M-66 and disable it.
In a fit of niceness, the commanding officer lets Sybel go rather than disappearing her.
The incident is covered up as a terrorist bombing.
