The son of a woman killed in the Air India plane crash has told the BBC "other remains" were found in her casket after her body was returned to the UK. Miten Patel, whose father also died in the crash, said the coroner identified the mixed-up remains and left him to worry: "How many others are in there?"

In one case, a coroner in London discovered that the DNA of several bodies had been co-mingled in one of the caskets, Healy-Pratt told UK news agency PA Media.

FAA Administrator Bryan Bedford said Thursday that the June crash of an Air India flight that killed 260 people does not appear to have been caused by a mechanical problem with the aircraft's fuel control switches, which have emerged as a major focus in the Indian government's investigation into the disaster.
