A Spicejet Boeing 737-800, registration VT-SYZ performing flight SG-8719 from Ahmedabad to Patna (India) with 85 passengers and 6 crew, was descending towards Patna when the crew stopped the descent at 6000 feet due to problems with the flaps. The crew determined that the runway in Patna would be too short and decided to divert to Varanasi. The aircraft climbed to FL140 for the diversion and landed safely on Varanasi's runway 27 at a higher than normal speed (about 170 knots over ground).
