Exercise London: a disaster exercise involving numerous casualties.

A large-scale disaster exercise was conducted to assess how one large community would handle such a situation - particularly, how it would deal with 150 casualties. The planning, undertaken by a subcommittee composed of representatives of all resource groups in the city, took more than a year. The deficiencies of the disaster plan detected during the exercise, which included a lack of trained personnel and various problems of communication, are now being corrected.
