Two sisters who made a surprise trip from London to visit their grandmother for her birthday are among the victims of the Air India tragedy.

Dhir and Heer Baxi, both in their 20s, travelled from the UK capital to Ahmedabad for the visit and were returning to Gatwick when their plane crashed just 60 seconds after takeoff.

Their heartbroken loved ones told today how they had lost 'everyone' after the 'young talents' were killed in the disaster.

Dhir was a designer for a degree in fashion design while Heer worked as a project leader in the investment and renewable energy sector. She had previously worked in Singapore, where the sisters are believed to have spent their childhood.

The Air India plane carrying 242 passengers crashed just moments after take-off from Ahmedabad Airport in the northwestern Indian state of Gujarat.
