On 14 January 2002, a Boeing 737-200, operated by Lion Air, attempted to take off from Sultan Syarif Kasim II airport, Indonesia, without flaps set after a failure to complete the before take off checks. The rejected take off was not initiated promptly and the aircraft overran the runway. The take off configuration warning failed to sound because the associated circuit breaker was so waorn that it had previously auto-tripped and this had not been noticed.
