Malenchenko and Whitson, together with visiting Korean astronaut Yi, who had been delivered to the ISS by Soyuz TMA-12, undocked from the station aboard Soyuz TMA-11 at 05:06 GMT on 19 April 2008. Following the deorbit burn at 07:40 GMT the aft service module of the Soyuz failed to separate and the spacecraft began re-entry in a reversed position, with the forward hatch taking the initial re-entry heating. As was the case with Soyuz 5 in 1970, the connections with the service module finally melted away, and the freed capsule righted itself aerodynamically with the heat shield taking the brunt of the re-entry heating. However the crew experienced a rough ride, a ballistic re-entry of over 8 G's force, smoke in the cabin, a failure of the soft landing system, and a very hard landing. They landed 470 km short of the target point at 50 deg 31" N, 61 deg 7" E at 08:29 GMT. A small grass fire was started at the landing point and the injured crew had to be helped from the capsule by passers-by. Malenchenko and Whitson suffered no permanent injury, but Yi was hit by Whitson's personal effects bag on impact and required physical therapy for neck and spine injuries. References: 2.
