 GEOG: Sean Miller is transferred from a prison in Southwark (in  London) to the high security unit on the Isle of Wight. This would  involve a land journey of 50 miles to the southwest, then a ferry  across the Solent. However, the ambush is depicted as occurring at  the Middlesbrough moving bridge, 200 miles north of London; and in  later dialogue its said to have been in Kent near the Channel,  which would be southeast of London and at least 70 miles from the  Isle of Wight ferry routes.
