Editor’s Letter
A VERY WARM welcome to our 31st issue, in which we
cover a typically broad selection of subjects, from the wildly
optimistic attempts of French aeronaut Louis Damblanc to
build a very early form of tilt-rotor (pages 44–52), to the story
of the epitome of the small, nimble Cold War jet fighter — the
Northrop F-5 — in Swiss Air Force service (including some of
author Peter Lewis’s eye-popping photography of the Tiger
over the Alps). Along the way, we also take in Tom Culbert’s
historical tribute to the intrepid founders of the “Hump”
wartime aerial route over the Himalayas (pages 20–29),
Lennart Andersson’s investigation into top secret inter-war
aerial chemical warfare experiments by Germany and the
Soviet Union (pages 68–74), and Professor Keith Hayward’s
political analysis of the
malheureuse
Anglo-French Variable
Geometry project
débâcle,
if you’ll pardon my French.
We also offer a welcome return to Amaru Tincopa’s
Wings
Over Peru
series (pages 54–66), in which he traces the career
of the Douglas 8A in Peruvian service, incorporating a level
of detail that was simply unavailable in English as little as a
decade ago. Being able to bring this material to a wider
audience, thanks to the sterling efforts of dedicated authors
and researchers like Amaru, is a genuine pleasure.
It is of particular poignance to me that this issue includes
the first part of an interview I conducted in 2005 with one of
Canada’s most distinguished airmen — Lt-Col Fern Villeneuve
AFC — because we received the sad news that he’d died,
aged 92, on Christmas Day 2019. Despite his extraordinary
career and remarkable achievements in aviation, Fern was
always, by account of everyone who knew him, just “one of
the guys” — and I feel privileged to have been able to call
him a personal friend.
Finally, before we head into the issue, another reminder
that everything we cover in
TAH
— including artworks and
book reviews — is included in our index, available (FREE!) as
a PDF download from the
TAH
website. Unlock your issues!
