Call for Papers CAHS Convention 2026 & Aviation Cultures Conference Mk VIII Wednesday 17 June to Saturday 20 June Save the date for the CAHS National Convention, which will take place in Kelowna, British Columbia, from Wednesday 17 June to Saturday 20 June. The convention is held in partnership with the KF Centre for Excellence and Aviation Cultures. We invite you to consider submitting a proposal to speak at the convention. Our combined convention is open to all: CAHS members, Aviation Cultures participants, university students, aerospace and aviation industry professionals, academics, professionals in aviation or heritage associations, and aviation enthusiasts of every kind. The focus will be on history, but we will consider proposals addressing current aviation or aerospace issues. Past CAHS conventions have included online attendance; the partnership with Aviation Cultures allows a greater online component and worldwide participation. All presentations will be available to both the in-person audience and online. Presentations can be made in person at the event, or live, online. CAHS regulars will find the familiar format for presentations, with presentations of around 45 minutes using PowerPoint or Google Slides formats. In addition, we welcome proposals for two new Aviation Cultures session formats: - ‘Blitz’ talks of five minutes to share short, unusual ideas, or current research; and
- Moderated panel sessions featuring 3 to 5 presenters on a single topic.
All sessions will include time for audience questions.
We encourage proposals on every aspect of Canadian aviation history, including general aviation, the aviation industry, space exploration, and of course, military and commercial topics. Drawing on the Aviation Cultures theme of ‘Spanning the Globe’, we also encourage proposals which are not directly related to Canadian history, but which will be of interest to Canadians.
Both the CAHS and Aviation Cultures are volunteer, non-profit organisations, and the event will only succeed with your support. Presenters are expected to register and pay for at least one day of the convention, online or in person. No re-imbursement can be offered for travel or other expenses. The deadline for submission is 15 January 2026, and speakers will be notified by the end of January. Please submit your proposal at this link. Questions may be addressed to CAHS Convention Chairperson Jim Bell, or Aviation Cultures Co-Organiser Edward Soye. |

The arrival of October means Thanksgiving is only a few weeks away. Did you know that the date wasn't originally fixed? It often fell in November before being set on the second Monday in October to avoid conflicting with Armistice Day after the First World War. I personally enjoy the Thanksgiving season, with the beautiful leaves at their height of turning colour (here in Ontario where I live) as the local farmers bring in their harvests. I also make sure I take the time to reflect on how thankful I am for the blessings - big and small - in my life. . I am grateful that, as a Canadian, I live in a country that benefits from the freedoms for which our Second World War veterans fought. As a military historian, I have an increased awareness of what our veterans had to endure and sacrifice to win the war. (If you wish to learn more about what brave Canadians did in the air force for Canada's future as they fought in various wars, please check out the CAHS shop for related books). During this Thanksgiving season, I hope you are able to spend time with friends, family, and loved ones and take stock of the blessings in your life. |

| Alberta is investing nearly $11 million to establish the Alberta Training Centre of Excellence for aviation and aerospace in Calgary. The 126,000 square foot facility, created in partnership with WestJet, CAE Inc., Mount Royal University, Calgary Airport and the Opportunity Calgary Investment Fund, is expected to train 6000 pilots and aviation professionals each year. The province says the project will create jobs, generate more than $400 million in industry activity over 15 years, and strengthen Calgary’s role as a global hub for aviation training and recruitment. |

Medicine Hat’s CAHS chapter joined forces with Canadian Owners and Pilots Association (COPA) Flight 171, and Gas City Aviators, on 13 September 2025 for a special Battle of Britain Fly-In Breakfast at Medicine Hat Municipal Airport. The monthly fly-in breakfasts already draw aircraft and visitors from across southern Alberta, but this edition featured something extra. The CAHS Chapter added historical displays, a screening of the 1969 film The Battle of Britain, and talks highlighting the air campaign and Medicine Hat Airport’s role as home to No. 34 SFTS during the British Commonwealth Air Training Plan. More than 75 people attended, enjoying breakfast, history, and aviation. A highlight came when a Harvard Mk IV, brought in from Rolling Hills, treated the crowd to two flypasts trailing smoke. The event wrapped up with calls to make the Battle of Britain breakfast an annual tradition. Story and photos by Wes Krause.

| Dr. Richard Gimblett has authored a comprehensive, fully illustrated survey of Canada's warship and maritime aircraft acquisitions from 1910 to the present day. This book is a chronological examination of when and why Canada has procured its some 50 classes of warships and a dozen aircraft types over the past 120 years, and how it has employed and disposed of them. |

ANSWER 1: “The Iroquois programme led to considerable advances in the use of titanium and knowledge and methods of working the material including welding. This knowledge led to breakthroughs in handling other materials such as zirconium, of interest to the nuclear industry. A variety of new alloys and complex applications were encountered which required improved fabrication and welding techniques. Development work was done on processes and procedures, such as the effect of stress relieving high temperature metals/materials by shot peening through quantitative creep and fatigue testing. The work done on plastic compressor blades with fiberglass and asbestos reinforcement represented a considerable advance with applications to both aeronautical, and commercial machinery. Work on turbine blade cooling involved investigation of forget and cast materials suitable for hollow structures.” Source: Arrow Countdown, pg. 47 (Zuuring) |

ANSWER 2: “A Canadian design known as the Fleet Fort had been developed to meet the need for an intermediate and advanced trainer, but it was not a success. While serving as an instructor at No.2 Wireless School, Shephard, Alberta, Jack Merryfield investigated fourteen forced landings by Fleet Forts in a period of little more than three months, “usually from defective oil lines, leaking oil tanks, or an overheated engine, etc.” During a solo flight near Shephard, Merryfield observed the fuel-tank cap on the starboard wing of his Fort slowly unscrewing because of the vibration. Acutely conscious of the fact that the exhaust pipe was also on the starboard side and that if the cap came off fuel might be sucked out in its general direction, he “lost no time returning to Shephard…” He landed safely. Surviving Forts were soon replaced by Yales and Harvards.” Source: Wings For Victory, pg. 124 (Dunmore) |

ANSWER 3: “On 16 April, Fauquier led eighteen Lancasters to Swinemunde against the Lutzow. Braving intense ground fire and suffering its last combat loss of the war, fifteen squadron aircraft bombed the capital ship with either Tallboys or 1000-pounders. All but two of the attacking Lancasters sustained flak damage, but three Tallboys had straddled the behemoth, one impacting between the dock and the ship’s moored side. However, on examination of post-strike reconnaissance photos, 617 Squadron was disgusted to see the giant warship sitting, apparently untouched, exactly where she had been attacked. However, two days later, Intelligence confirmed that one of the Tallboys had ripped a giant hole in her hull and that she had settled to the bottom at her moorings in less than fifty feet of water.” Source: No Prouder Place, pg. 431 (Bashow) |
