The plane was shot down over Ukraine, killing everyone on board.The 47-year-old Dalziel was not travelling on a South African passport, but a British one.
He was a South African citizen who was born in Zimbabwe.He leaves behind his wife and two sons, aged four and 14.
Dalziel moved to Malaysia last year to take up a position with CHC Helicopters.His brother-in-law, Shane Hattingh, says he moved there to spend more time with his family.
He says Dalziel had been flying choppers all over the world, and had been away from his family for about 10 years.It's been reported that there may have been a second person, also with South African ties, aboard the flight, but this is yet to be confirmed.
Nelson Kgwete from the Department of International Relations says the government will assist where necessary.
