The two expatriate brothers lost their parents on that fateful day. Now, they fear they would miss the chance to see their parents one last time as their mother's body is yet to be identified.

“It's always hard to even anticipate how it feels to have both your parents gone,” said Md Kaisar Imam, elder son of the retired couple -- Md Hasan Imam and Begum Hurun Nahar Bilquis Banu.

The couple were among the 51 who died in the US-Bangla plane crash in Nepal on March 12. They planned the tour to celebrate their retirement with their friends.

“A vast emptiness is always driving me now. Everything will be in its place except for the two most precious persons of our lives,” he added.

A retired joint secretary, Hassan's name is in the final list of identified bodies but the body of Bilquis, a retired teacher of Rajshahi, is not in a state to be identified.

Therefore, the body would go through a DNA test. A team of Criminal Investigation Department (CID) already reached Kathmandu to collect DNA samples of the victims which would be cross-matched with samples of the victims' family members at the CID lab in Dhaka. The entire procedure will take eight to 10 days, said sources.

“If so, one of us will miss the chance to bury our parents as we must return to our work in Canada by April 2,” Kaisar said.

The two brothers work as software developers in Canada. One of their cousins is now in Nepal to identify the bodies.

Just a day before the crash, Kaisar had his last conversation with his mother. He was pulling her leg as Bilquis never agreed to fly to Canada to meet her sons due to her flight phobia but this time she was ready to embark on a plane journey.

It was 9:00am on Monday in Alberta, some seven hours after the plane crash-landed in Nepal, when the brothers first got the news.

“I thought it must be some other plane. But anxiety engulfed me,” Kaisar said.

Soon, they started getting phone calls from relatives and friends. Finally, one of his uncles from Dhaka asked them to start for Bangladesh immediately. “I heard some passengers survived the crash and prayed that my parents were among them,” he added.

They caught a Turkish Airlines flight from Alberta to Dhaka at 4:00pm on that very day, but reached Dhaka on Thursday morning as they missed a connecting flight.

 Kaiser and his younger brother Md Toukir Imam, 26, have been living in Canada for last five and three years respectively. “We want to visit our home in Rajshahi. But, we are afraid of seeing the empty house. There will be no one to welcome us, to embrace us with love and affection.”
