Air India Boeing 787 bound for London with 242 people aboard has crashed at India’s Ahmedabad Airport, killing at least 290 people in one of India’s worst airline disasters in decades, officials said, with one survivor reported among the passengers.

The plane, heading to Gatwick crashed when the aircraft was taking off from Ahmedabad airport in India.

Video of the plane from right before the crash does not show any smoke or fire, so he said it does not appear that a bird strike was an issue. And even if the plane lost one engine, the second engine should be able to carry it aloft, an expert said, per The Associated Press.

According to Vidhi Chaudhary, a top state police officer in Ahmedabad, Medical students who were in a college hostel when Air India Flight 171 hit the building are among the dead.

‘Most of the bodies have been charred beyond recognition,’ she said.

The plane crashed into the hostel of BJ Medical College, located in a residential area outside the airport, during lunch hour. Officials said part of the plane fell on the college’s dining area.

Doctors in the building are recorded among casualties.

It remains unclear why Air India Flight 171 was having difficulty climbing as it took off from the airport in Ahmedabad.
