The UH-1 helicopter, which was on a training flight, ended up on a street in Istanbul's Sancaktepe neighborhood — on the Asian side of the city that straddles two continents — while trying to make an emergency landing, Defense Minister Hulusi Akar told reporters at the scene of the crash.
The helicopter appeared to have turned over and debris from the crash scattered around the street, according to video footage from the scene. Akar said the pilot appeared to be trying to land the helicopter, which was on its way to the air force base of Samandira, near Sancaktepe, on an empty plot of land in order to prevent civilian deaths.
"They tried to make an emergency landing for a reason that we do not know yet," the minister said. "(The helicopter) was very close to the air base, but unfortunately could not make it back." The dead servicemen included two officers and two non-commissioned officers, Akar told reporters. The injured serviceman, a sergeant, was in serious condition and facing an operation.
An investigation into the cause of the crash has been launched, he said.
