The Boeing 787 was travelling from Amritsar and Delhi last Thursday when it experienced more than 10 minutes of turbulence.
The inside panel of the window fell off, but the outside panel remained intact — which meant there was no depressurisation of air, and no risk of anything or anyone being sucked out through the window.
Footage shows a flight attendant pushing the internal window panel back into place and reassuring an audibly distressed passenger at the window seat.
Three passengers were reportedly injured and taken to hospital upon arriving in Delhi, a senior Air India official told local media.
One passenger received stitches after hitting their head on the overhead panel, while other two were treated for minor injuries.
“This was a freak high level turbulence. AI and Directorate General of Civil Aviation (DGCA) is probing it,” a senior Air India official said.
