A Turkish training plane has crashed killing the pilot in Turkey’s south-eastern province of Adiyaman early Wednesday.

Two training planes, which belonged to Gaziantep University, had taken off from the Gaziantep Airport in the early hours on June 27, Gaziantep University’s rector Ali Gür was quoted as saying by state-run Anadolu Agency.

“Trying to complete a 38-hour long flight, the front flying plane crashed, killing our trainee pilot,” said Gür.

“The other plane and pilot are fine,” he said. The cause of the crash has yet to be ascertained.
