On the morning of 12 February 1998, a Sudan Air Force Antonov An-26 turboprop attempted to land at Nasir Airport. The craft overshot the end of the runway and slid into the Sobat River.[3] The Sudanese government announced that fog and strong winds had caused the crash.[4] The SPLA's spokesman in Nairobi announced that the crash had not been an accident, but had been caused by an SPLA attack.[3]
