Fearing that the Army might take over, Sharif attempted to dismiss his own appointed Chairman of Joint Chiefs of Staff Committee General Pervez Musharraf and install an ISI director-general Lieutenant-General Ziauddin Butt as Chief of Army Staff. Musharraf, who was out of the country, boarded a commercial flight to return to Pakistan, but senior army generals refused to accept Musharraf's dismissal. Sharif ordered the Karachi airport to prevent the landing of the airline, which then circled the skies over Karachi. In a coup d'état, the generals ousted Sharif's administration and took over the airport. The plane landed with only a few minutes of fuel, and Musharraf assumed control of the government. Sharif was put under house arrest and later exiled.
