A two-seater aircraft used by the NCC made an emergency landing on the Eastern Peripheral Expressway in Ghaziabad on Thursday, officials said.
The incident took place around 1.45 pm on the highway near Sadarpur village, Ghaziabad Senior Superintendent of Police (SSP) Kalanidhi Naithani said.
"The plane had two pilots onboard and both of them are safe," Mr Naithani told PTI.
"The incident is said to have occurred due to a technical glitch in the plane but its cause could be ascertained by authorities concerned only," the officer said.
The left wing of the aircraft, enroute to Hindon airbase from Bareilly, suffered some damages in the incident but traffic movement on the highway remained normal, he said.
The National Cadet Corps (NCC) has been using the aircraft for training, Deputy Superintendent of police (Sadar) Anshu Jain said.
