The son of an Air India plane crash victim, who was sitting one row behind the man who survived, has told Sky News he will relive “her last moments” until the day he dies.

Manju Mahesh Patel, 79, was on the London Gatwick-bound plane when it crashed in Ahmedabad shortly after take-off on Thursday.

She was sitting in seat 12D on flight AI 171, the row behind the only person to survive the crash who was sitting in 11A.

In an interview with Sky News, Chirag Mahesh Patel, Manju’s son, said he hopes his mother’s death was “instant” and “painless”.

“To the day I die I will think, ‘what were her last moments?’,” he said.

Pointing to a framed family photograph of Ms Patel at the family home, he added: “I want to remember mum like this.

“I don’t want to have to go and identify a burnt corpse, your own parent. How does someone, how do you ever get over that? That will be with me, that’s with me for life.”

Ms Patel had been staying in Ahmedabad for the past few months doing charity work at a temple. She was due to be picked up by her son at Gatwick on Thursday night.

In tears, Mr Patel described his mother as “very strong” and a woman “who really loved her family”.

“The thing about my mum,” he said, “is her bond with her faith. It’s unbreakable.

“She had ultimate faith… and in times of stress she would always say God’s name… So, I know that upon take-off, I know that she was saying his name.”

Mr Patel said that when he realised his mother was on the flight it was just “a normal day” and “it didn’t seem real”.

He said the last time he had spoken to her he had reminded her to take her diabetes medicine and had then missed a call from her at 4am to say she had arrived at the airport.

He described “the most heartbreaking thing” was how much Ms Patel was looking forward to seeing her grandchildren, saying “it was everything to her”.

She had told him she packed her suitcase with lollipops for her six-year-old grandson, and special crisps for her 15-year-old older grandchild.

“It’s unimaginable even in my worst nightmare,” he said. “And the thing that kills me… is she was so looking forward to seeing us… she kept saying I bought this for you, I bought that, I bought the things for the kids.”

Mr Patel and his wife are due to fly to India on Saturday night to provide a DNA sample to help identify his mother’s remains.

He expressed his anger at what he called a “disgusting” and “appalling” lack of communication from Air India – which he said passed his details to a hospital but never contacted him personally.

He described feeling “neglected” by the airline, which he said would only offer him an Air India flight – and no help organising accommodation.

Mr Patel said he refused to get on the Gatwick flight back to Ahmedabad and has booked with another provider to travel to India instead.

“I said [to the airline] all of this happened on Thursday, you’re telling me on Friday afternoon, do you want that flight this evening? That one crashed? The one coming back where 172 goes out? They asked do you want Air India 172? I said how can you ask me that. My mum just died on Air India.”

Mr Patel said he wanted “answers” and transparency in any air accident investigation.

Air India said in a statement: “Air India stands in solidarity with the families of the passengers who tragically lost their lives in the recent accident. Our teams on the ground are doing everything possible to extend care and support during this incredibly difficult time.

“As part of our continued efforts, Air India will be providing an interim payment of ₹25 lakh or approximately £21,000 each to the families of the deceased and to the survivor, to help address immediate financial needs. This is in addition to the ₹1 crore or approximately £85,000 support already announced by Tata Sons.

“All of us at Air India are deeply saddened by this loss. We mourn with the families, loved ones, and everyone affected.”

The company’s chief executive and managing director Campbell Wilson said in a video message posted on social media that over 200 “trained caregivers” were now in place to offer dedicated assistance to families, along with counselling and other services.

He said Air India was in the process of completing precautionary safety checks on Boeing 787 aircraft as directed by regulator the Directorate General of Civil Aviation (DGCA), which would “be completed within the timelines prescribed by the regulator”.

Mr Wilson said he had also visited the crash site and said other members of the management team would remain present “for as long as it takes”.

The aircraft’s data recorder, often referred to as a black box, has been recovered and will form part of the investigation into the worst aviation crash in a decade.

‘He was too young’: Families grieve those lost in Air India crash

By Lisa Dowd, Midlands correspondent, in Derby

It was an emotional service at Derby’s Geeta Bhawan Hindu temple, as dozens of friends, colleagues and neighbours gathered to remember Dr Prateek Joshi, his wife Komi, their daughter Miraya, and twin sons Nakul and Pradyut.

Some wiped tears from their eyes, as a colleague was asked spontaneously to pay tribute to Dr Joshi, who had been bringing his family to live in the city, when the Air India flight they were on crashed seconds after take-off.

“He was too young, too much still to give, too much still to be done, too much to offer,” his friend told worshippers.

“He was taken from us in a very cruel and abrupt way, and his family as well, and we all think about his family back in India who is missing a son, missing a daughter-in-law and missing all their grandchildren who they’ll never see growing up.”

Derby South MP Catherine Atkinson said Dr Joshi, who was a radiologist at the Royal Derby hospital, had been “contributing to our NHS and the health of so many in our city and beyond”.

She said his wife was a pathologist who had resigned from her job in India.

“I won’t forget the photograph of them on the plane, full of optimism about their new adventure,” she said, as her voice broke.

“The losses make us all hug our families and loved ones a little closer and remind us how precious our time together is.”

Dr Joshi was described as a “warm, smiling man, full of joy” who enjoyed walking in the Peak District and who had discovered “a love of fish and chips”.

His neighbour and colleague Manoj Ramtohal told Sky News Dr Joshi always had time for people.

“He was very caring and very polite, very friendly, you couldn’t meet a better man than Prateek,” he said.

“We lost a very, very talented doctor.”
