 The tank Kryten uses in the seventh series episode "Beyond a Joke"  had previously been used in the James Bond film  _GoldenEye (1995)_ (qv). The number shown on the tank, 343, is the  same in both. The tank arrived late after being caught in traffic on  the M25 motorway, and the explosion it created when fired was enough  to set off car alarms and provoke many complaints from nearby  residents.
