Now he knows they did. Oakville resident John Barry French and several of his colleagues from the University of Toronto's Institute for Aerospace Studies were recently recognized with the Canadian Air & Space Pioneer Award from the Canadian Air & Space Museum for their work during the Apollo 13 incident. Like the rest of the world, French, a professor at the Institute of Aerospace Studies, had been following the Apollo 13 drama as it unfolded in April of 1970, not knowing that he would soon become a part of it. Four days into its journey to the moon, one of the Odyssey spacecraft's oxygen tanks exploded, causing widespread damage and leaving the three astronauts inside in a desperate situation. On April 16, 1970, a staff meeting at the Institute for Aerospace Studies was interrupted by a phone call. "It was Grumman Aerospace Corp., the people who designed the lunar excursion module," said French. "I got this phone call and they said, `Look would you be willing to help?' and I said, `Sure we will, I'll go tell the staff about it." The call was a surprise to say the least, but French quickly mobilized a team of six people to tackle the problem. NASA had devised a plan to use the lunar excursion module as a lifeboat, which would re-enter the Earth's atmosphere after being separated from the rest of the ship. The plan called for the detonation of a prima cord explosive ring to split the two spacecraft components, but there was concern about the amount of air present in a tunnel the astronauts used to move between them. Figuring out what the proper air pressure should be to safely push the two components apart is where French and his team came in. While determining how much air should be left in the spacecraft tunnel may seem DAVID COOPER / TORONTO STAR LIFESAVERS: Ben Etkin, Barry French, of Oakville, and Phil Sullivan were recently honoured for their work in saving the lives of the Apollo 13 astronauts. trivial, French pointed out, but "They used ours and there getting it wrong could have led weren't any others.
