on Thanksgiving Day, a huge fire swept through the offices of Northwest National Bank of Minneapolis, destroying bank transaction records and data processing facilities. It was described as one of the worst fires in the city's history. Yet the following Monday, bank employees were back on the job in new quarters-handling deposits, withdrawals, investments, loans, and other routine bank transactions. The fire could have threatened the bank’s ability to remain recovery plan. Because a record of nearly every bank transaction was stored elsewhere in computers or on microfilm, the bank lost few, if any, important records. The day after the fire, computers at a local service bureau were hard at work making new copies of the destroyed records. The recovery plan provided bank executives with a detailed blueprint for lining up new office space, replacing computer equipment and supplies, procuring new office equipment, and making other arrangements essential to the continuation of Northwest's banking operations.
