With 260 casualties and only one surviving passenger, the Air India 171 crash is one of the deadliest aviation incidents in recent history — and so far it’s proving to be one of the most frustratingly opaque.

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.

The mistakes were found after DNA testing by a coroner in London. The Indian government said bodies of the Flight 171 victims “were handled with utmost professionalism.”

A preliminary report about the Air India jetliner that crashed in June did not say a broken cockpit seat was to blame, contrary to what has been claimed in posts online.

Following the Air India AI171 crash, UK families allege DNA mismatches in repatriated remains, suggesting a mix-up of victims. They accuse Air India of pressuring them to sign complex compensation documents.

The families of some Air India victims from the United Kingdom were given the wrong remains, according to a lawyer.

A Mumbai-bound Air India Express plane, with around 160 passengers onboard, aborted takeoff due to a technical snag at the Delhi airport on Wednesday evening, according to a source.

Talks on the matter reportedly began earlier this year --- slowing briefly after the devastating Ahmedabad plane crash.
