## U-2 Crash in Thailand
Flights by Detachment C U-2s over Tibet and western China continued during the first half of 1960 under Operation TOPPER. The first mission on 30 March was very successful. The second mission on 5 April took good photographs but encountered mechanical problems. At the start of the mission, the landing-gear doors failed to close completely, resulting in increased drag and higher fuel consumption. With no fuel gauge to warn the pilot of the critical fuel situation, the aircraft ran out of fuel far short of Ta Khli, forcing the pilot to make a crash landing in a rice paddy. The area was inaccessible to large vehicles, and the plane, article 349, had to be cut into pieces in order to remove it. With the help of local villagers, the retrieval team dissassembled the aircraft for transport to the base, where the pieces were loaded onto a C-124 under cover of darkness. The crash and subsequent recovery of the U-2 did not attract the attention of the press; there was only one report in a local Thai newspaper, which simply referred to the crash of a jet plane. In appreciation for the assistance provided by the villagers,
The loss of two aircraft in slightly more than six months left Detachment C with just two aircraft. Fortunately, the level of mission activity remained low because Detachment C was no longer conducting overflights of the Soviet Union.
gave the headman funds to build a new school.
## End of Detachment C Operations
One important remaining mission was high-altitude air sampling (HASP), in which specially equipped U-2s gathered upper-altitude air samples to look for evidence of Soviet nuclear testing. The direction of the prevailing winds made Detachment C ideally situated for this activity, which began in the fall of 1958 and continued in 1959. In late April 1960, Detachment C was preparing to stage to the Philippines to conduct additional air-sampling missions, when the loss of Powers' U-2 temporarily halted all U-2 activities.
