Search boats continue to hunt for wreckage of a Kenya Airways plane that plunged into the waters off Ivory Coast Sunday.

Workers have not found the main part of the plane or the black box flight data and cockpit voice recorders.

So far, 86 bodies have been recovered.

The Airbus 310 fell from the sky one minute after taking off from Abidjan airport on a flight destined for Lagos, Nigeria.

The crash killed most of the 179 people on board, including two Canadian missionaries from Hamilton. Incredibly, 10 people survived, including one man who swam for four hours to shore.

The Canadians have been identified as 45-year-old Bob Chapman and his 52-year-old wife Ruth Chapman, who were missionaries in Africa. They were travelling home to Nairobi, Kenya where they had been living since June. The couple are survived by a 19-year-old daughter.

The Chapmans worked for a Christian group that promotes literacy by translating the Bible into different languages.

A decade ago, their two sons died from malaria in Africa.

"The temptation is of course to question and to wonder why it had to happen," Bob Chapman Sr. told CBC Radio Tuesday. "However, God has consigned to us the declaration we are to go into the world and preach the gospel to every creature.

"And that was their firm conviction and confirmation was given, so there are no regrets."

The remains of the two Canadians have not been found, but Chapman Sr. says they wanted to be buried in Africa.

A memorial service will be held Feb. 12 in Hamilton, Ont.
