Pretty faithful to the actual events.

Except skipped the part when the 6th terrorist was identified on the lawn, was marched back into the embassy by an SAS trooper with the intention of having a burst of MP5 put in his computer. Mate tapped him on the shoulder and pointed out the tv news cameras all around the plot.

Apparently the SAS team were more upset that they let one terrorist live than the fact that they got all but one hostage out alive. Geezers.

That and the 2 Iranian scumbags on the 4th floor who threw their weapons out the window, waved white flags and ended up with around 100 bullets in them each. The good old days. Maggie ruled.
