DeMarco, along with Roughriders teammates, Becket, Sturtridge, and Ray Syrnyk, were passengers on Trans-Canada Air Lines Flight 810 with another CFL player, Calvin Jones, of the Winnipeg Blue Bombers.[1] All five players were present at the 1956 East–West All-Star game in Vancouver, British Columbia, and were headed back to their respective teams' home cities.[1] The five players were accompanied by 54 other passengers, and 3 crew members who all lost their lives in Western Canada's worst aviation disaster on December 9, 1956.[1] The crash is the subject of the 2012 documentary The Crash of Flight 810, part of TSN's Engraved on a Nation series of eight documentaries celebrating the 100th Grey Cup.[3][4]
