A Thai Airways International flight heading to Singapore turned back to Bangkok on Sunday after the pilot noticed a crack in a cockpit window shortly after takeoff.
THAI issued a statement on Monday saying the pilot of flight TG401 from Bangkok to Singapore on Sunday decided to return to Suvarnabhumi airport after the captain detected a crack in the outer layer of a leftside cockpit window.
The windows have three layers of acrylic glass.
The plane had departed Suvarnabhumi at 7pm on Sunday. The plane touched down safely on its return to the airport.
Passengers were transferred to another plane, special flight TG401D, which departed from Suvarnabhumi at 9am on Monday. It landed at Changi airport, Singapore, at 12.25pm local time (11.25am Thailand time), the announcement said.
THAI uses a twin-engine Airbus A330-300 on the Singapore route.
