Every time Aryan Asari heard the sound of an airplane, he would darted to go out of the house.

Spotting plane was a hobby for him, his father is merryI Asari said. Aryan loved the sound of the engine roar and then rises loudly as the aircraft cruel over it, leaving the knock of contraception in the sky.

But now, very thought about it makes him sick.

Last Thursday, 17-year-old, was on the roof of Mr. Asari’s house in Ahmedabad city, making videos of an airplane when an Air India Dreamliner 787-8 crashed out of his eyes and exploded in flames, killing 241. About 30 people were also killed on the ground.

At that moment, Aryan captured his phone.

“I saw the plane. It was going down and down. Then it crashed in front of my eyes and crashed,” he told BBC Gujarati in an interview earlier this week.

The video, which is now an important clue for investigators trying to find the cause of the accident, has sent waves through news media and put Aryan – a high school student – at the center of one of the worst aviation disasters in the country’s history.

“We have been swept away by the requests for the interview. The reporters have asked him to talk around my house day by day,” Mr. Asari told the BBC.

This phenomenon – and after that what has been followed – Aryan had a “devastating effect”, which he saw. “My son is so scared that he has stopped using his phone,” said Mr. Asari.

A retired army soldier, who now works with the city’s metro service, has been living in a neighborhood near Sri Asari Airport for three years. He recently moved into a small room located on the roof of the three -storey building, with a clear view of the city’s horizon.

His wife and two children – Aryan and his elder sister – live in their ancestral village near the border between the states of Gujarat and Rajasthan.

“This was the first time Aryan in Ahmedabad. In fact, it was the first time in his life when he left the village,” said Mr. Asari.

“Whenever I call, Aryan asks if I can see the plane from our roof and I will tell him that you can see hundreds of them falling into the sky.”

Aryan, he explained, was an airplane enthusiast and preferred to see them because they flew into the sky over their village. The idea that he could see him very closely from the roof of his father’s new house, he was very attractive to him.

One occasion presented herself last week when Mr. Asari’s daughter, who wants to become a police officer, traveled to Ahmedabad to write the entrance exam.

Aryan decided to go with him. “He told me that he wants to buy new notebooks and clothes,” said Mr. Asari.

Brothers and sisters arrived at their father’s house around noon on Thursday, about an hour before the accident.

The family had lunch together, after which Mr. Asari left to work, left the children at home.

Aryan stepped on the roof and started making house videos to show his friends. When he saw the Air India plane and started filming it, he told BBC Gujarati.

Aryan soon felt that something was not right about the aircraft: “It was moving, left and right,” he said.

As soon as the aircraft went down the spiral, he kept filming it, unable to understand what was going to happen.

But when thick smoke filled the air and the fire came out of the buildings, he finally felt what he had just seen.

He sent a video to his father and called him.

“He looked so frightened -” I saw it, I saw it crash, “he told me and kept asking me what would happen to him. I asked him to sit tightly and don’t worry,” Mr. Asari said. “But he was with himself in the horror.”

Mr. Asari also asked his son not to share the video. However, very scared and shocked, Aryan sent it to some of his friends. “The next thing we knew, the clip was everywhere.”

The next few days had a bad dream for the family.

Neighbors, journalists and camera persons, requesting to talk to Aryan, filled the small houses of Mr. Asari with floods day by day. “We could not do anything to stop them,” he said.

The family also received a visit from the police, which took Aryan to the station and recorded his statement.

Mr. Asari clarified, unlike the report, Aryan was not detained, but the police questioned him for a few hours.

“My son was so upset till then we decided to send him back to the village.”

Back home, Aryan has resumed the school, but “still doesn’t feel like herself. His mother tells me that every time his phone rings, he gets scared”, Mr. Asari said.

“I know he will recover over time. But I don’t think my son would try to search for an airplane again in the sky,” he said.
