The National Airborne Service Corps (NASC; traditional Chinese: 內政部空中勤務總隊; simplified Chinese: 内政部空中勤务总队; pinyin: Nèizhèngbù Kōngzhōng Qínwù Zǒngduì; Pe̍h-ōe-jī: Lāi-chèng-pō͘ Khong-tiong Khîn-bū Chóng-tūi) is the sole agency of the Republic of China (Taiwan) that operates aircraft and helicopters besides military and paramilitary units.

The agency is responsible for executing and providing aerial support for search and rescue, disaster relief, emergency medical service, transportation, monitoring, reconnaissance and patrol.

[2] In July 2000, four workers employed by the government was stranded on a shoal of the Bazhang River when they are performing riverbed maintenance construction project and the flood strikes.

While the search and rescue personnel already arrived, they had no helicopter to fly, so they could do nothing but standing on the riverbanks, watching them drowning, and the whole situation was aired live on multiple news channels in Taiwan.

An increase in the amount of land accessible to recreational hikers which coincided with the boom in hiking contributed to the high level of callouts.
