The Air India flight fell from the sky on Thursday and killed at least 270 people in Gujarat state, officials said Saturday.

Multiple Indian agencies, including the National Security Guard (NSG), National Disaster Response Force (NDRF), Indian Air Force, forensic teams, fire and rescue services are inspecting the wreckage of the London-bound Air India jet, which crashed into the rooftop of a doctors’ hostel in Ahmedabad. The area remains fully cordoned off.

Thursday’s deadly crash struck at Boeing’s most ambitious and one of its most commercially successful jet programs — a coveted airplane that airlines the world over gladly wait years to receive.
