Taipei: Taiwan's air force said Wednesday it has grounded all its Mirage jets as it searched for a pilot who went missing while conducting a training mission in one of the French-made fighters.
The single-seat Mirage-2000 flown by Captain Ho Tzu-yu disappeared from the radar at 6:43pm (1043 GMT) on Tuesday off the northeast coast of the island, 34 minutes after taking off, according to the air force.
Authorities dispatched 17 military planes as well as 10 naval and coastguard vessels to conduct a search but there has so far been no sighting of the missing plane, it said.
"We hope Ho can be safely rescued soon," said Lieutenant General Chang Che-ping, the air force's deputy chief.
All Mirage jets have been grounded since the incident, Chang said.
Chang described Ho as an "excellent pilot" and said there was no sign of any problems or irregularities after he took off from a base near the northwestern city of Hsinchu .
Ho graduated from the Air Force Academy in 2013 and had accumulated around 227 hours in the Mirage-2000, the air force said.
Chang declined to comment on reports that Ho's health may have been a factor in the disappearance, saying an investigation into the cause of the incident was still under way.
He confirmed that Ho had taken time off work in 2015 on health grounds but declined to elaborate.
Taiwan purchased 60 Mirage 2000-5 jets in 1992 from France in an arms deal that upset China.
Beijing claims sovereignty over Taiwan even though the two sides split in 1949 after a civil war and is fiercely opposed to the island developing its military capability.
There were five accidents involving Mirage fighters in Taiwan between 1999 and 2013, killing three pilots.
In 2012, Taiwan temporarily grounded all its Mirage jets after one of its pilots died while conducting a training mission in France.
