Two pilots and eight on-board technicians of the Indian Border Security Force (BSF) were killed after a Beechcraft Super King B-200 aircraft crashed just outside Indira Gandhi International (IGI) Airport in Delhi.
A source was quoted by The Times of India as saying that the 'aircraft took off from IGIA's main runway (number 28) towards the Dwarka side'.
The source said: "Within a minute or two of getting airborne, pilots are handed over from the tower to the departure control radar.
"Pilots tell them their altitude and aircraft identification number called squak. But there was no contact at all with the BSF aircraft after take-off.
"The plane had gone only about 700ft high during its short-lived flight."
After taking-off from IGI airport, the pilots sought permission for an emergency landing when they noticed some technical problem with the plane.
The airport fire trucks were alerted, but the ATC lost contact with the flight.
The 21-year-old ten-seater twin-engine Beechcraft was to land on the runway when it lost control and crashed outside the airport's boundary wall bursting into flames.
According to the news agency, the technicians were on their way to Ranchi to repair a Mi-17 V5 helicopter when the incident occurred.
Indian Union Minister of State Civil Aviation Mahesh Sharma said that an investigation has been ordered.
