The original DH.60 Moths had straight wings, the upper wing passing directly over the front cockpit. When the type was adopted by the RAF, the Air Ministry asked for escape from the front cockpit to be made easier, so the top wing was moved forward to clear the cockpit. This moved the CP forward by an unacceptable amount, so the wings were swept back to correct this.cheers,         Robin.</blockquote>
