BEIJING (AP) — A Taiwanese air force pilot was killed in an aerial collision between two training jets on Tuesday.

One jet was not badly damaged, and the pilot flew it back to base safely.

The other pilot bailed out after the midmorning collision in the southern county of Kaohsiung. He was taken to a hospital where he was declared dead. The air force identified the dead pilot as 37-year-old Chuang Pei-yuan.

No damage or injuries were reported on the ground. The planes involved were Taiwanese-made AT-3 advanced jets used by the air force’s Thunder Tiger aerobatics team and were on a routine training mission.

Air force academy Superintendent Chang Yan-ting told reporters the cause of the accident was under investigation.
