What was Operation Yellow Ribbon?

Operation Yellow Ribbon was the Canadian aviation operation that diverted and accommodated 226 inbound transatlantic flights to 17 Canadian airports on September 11, 2001 after United States airspace was closed in response to the al-Qaeda terrorist attacks. About 33,000 passengers and crew spent several days stranded in Canadian communities, with about 6,600 in Gander, Newfoundland alone (a town with a population of about 10,000). Operation Yellow Ribbon is widely celebrated as a moment of Canadian generosity and competence under extreme pressure.

The operation was triggered by US Federal Aviation Administration order SCATANA (Security Control of Air Traffic and Air Navigation Aids) issued at 9:42 AM Eastern Time on September 11, 2001, closing US airspace to commercial traffic. The closure left hundreds of inbound transatlantic flights from Europe, the Middle East, and elsewhere with insufficient fuel to return to their origin airports. NAV Canada (the private not-for-profit corporation that operates Canada's civil air traffic control) and Transport Canada coordinated the diversion to Canadian airports.

The diverted flights landed at 17 Canadian airports: Halifax (47 flights, about 8,300 passengers); Vancouver International (39 flights); Gander (38 flights, about 6,600 passengers); Stephenville (8 flights); St. John's (8 flights); Toronto Pearson (15 flights, mostly diverted from US destinations); Moncton (6 flights); Calgary (12 flights); Edmonton (4 flights); Goose Bay (8 flights); Montreal-Mirabel (8 flights); and others. About 33,000 passengers and crew were accommodated in Canadian communities for between two and five days while US airspace remained closed.

The Gander response is the most celebrated case. The town's residents and the smaller communities of Gambo, Glenwood, Lewisporte, Norris Arm, and Appleton accommodated the stranded passengers in homes, schools, churches, town halls, the Knights of Columbus hall, the Lions Club, and other community buildings. Local residents fed, sheltered, and entertained the 'plane people' for five days. Stories of Newfoundland hospitality produced the Tony Award-winning Broadway musical 'Come from Away' (premiered La Jolla, California 2015, Broadway 2017, made into a 2021 film). About 7,000 passengers also stayed in Halifax, with similar accounts of community generosity. After the closure was lifted on September 13 and 14, 2001, US airspace gradually reopened. By September 15 the last of the diverted flights had departed. Operation Yellow Ribbon is regarded as a model of efficient civilian air-traffic control crisis response and remains a lasting symbol of Canadian-American friendship.
