Awwal 17, 1432 H / April 21, 2011, SPA -- The head of Zimbabwe's debt-ridden state airline says pilots have resumed flying, ending a monthlong strike over pay and allowances, according to AP. Chief Air Zimbabwe executive Innocent Mavhunga says pilots reported for duty Thursday after reaching «an amicable agreement» with management and the transport ministry. He refused to give details of the deal. The airline's 49 pilots were demanding $4 million in unpaid salaries and allowances. They grounded the airline March 22 in the second strike in the past six months. Chartered carriers were hired to fly domestic and regional routes. Long-haul flights to London and Asia were abandoned.
