AHMEDABAD, India (Reuters) -Officials from the U.S. National Transportation Safety Board (NTSB) surveyed the site of Air India plane crash that killed at least 271 people, sources said on Sunday, with families continuing to wait for DNA profiling results to identify charred bodies.

Doctors in India say 270 bodies have been recovered from the site of Thursday's plane crash in Ahmedabad. The London-bound aircraft crashed into a residential area shortly after take-off killing all but one of the 242 passengers, a 40-year-old British man.

The London-bound Boeing 787 struck a medical college hostel in a residential area of Ahmedabad minutes after takeoff Thursday, killing 241 people on board and at least 29 on the ground. One passenger survived.
