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.
