In collaboration with Guinness World Records, in celebration of its Centennial and in commemoration of the men and women who have, and continue to, serve Canada at home and abroad, the RCAF will attempt to break the World Record for most landmarks illuminated in 24 hours.
We encourage Canadians across the country to join in this campaign, and light up their cities, businesses, and homes in blue, and to share photos on social media using the hashtags #RCAF100 and #100YearsOfFlyingBlue, in support of the Royal Canadian Air Force, and its personnel.
