An Aquila Airways Short S.45 Solent flying boat crashed while on approach to Southampton, United Kingdom, resulting in the loss of 45 lives and the survival of 13. The aircraft was banked 45 degrees to the right during its return flight, impacting a quarry between Chessel and Brook. The accident was caused by a stoppage of the No.3 engine at a time when the No.4 engine was stopped, potentially due to an electrical failure in the fuel cut-off actuator circuit or accidental operation of the cut-off switch.An Aquila Airways Short S.45 Solent flying boat crashed while on approach to Southampton, United Kingdom, resulting in the loss of 45 lives and the survival of 13.
