Three weeks after an Air India Boeing 787 crashed, investigators are still piecing together what went wrong. In the meantime, aviation safety experts have begun to narrow their thinking.

Spooked by the Air India plane last month that crashed seconds after departing from the Ahmedabad airport, private jet owners who have aircraft registered at the facility are doubling down on safety precautions.

There is no evidence that the sole survivor of the Air India crash that killed 260 people in June, Viswashkumar Ramesh, was arrested by police shortly after the incident, contrary to posts shared on social media.
