Review of The Terrorists

I thought the story flowed nicely and as I watched it I had the feeling it may be one of those good sleepers I had missed in the past. Really most of the actors were weak...but Connery and especially McShane were good. I have to say the ending made no sense at all...and when that happens you wonder why you watched the movie. Did I miss something or were both Connery and McShane(Deadwood) after the same guy. If so why did they fight in the plane....I may have missed something but weren't they basically on the same side? Were the hijackers on the plane all working for the Britsh? Just an absolutely bad ending to a movie that actually had some potential.
