With a bit of luck, you may also see this beautifully restored de Havilland Moth. This airframe got involved in Brazilian revolutionary shenanigans almost 100 years ago.

The leading airplane in this photo is the very Jungmeister on which Aresti developed the Aresti Catalog. If you are an aviation enthusiast visiting Madrid, I strongly recommend doing so on the first Sunday of the month and visiting the monthly airshow at Cuatro Vientos.

Despite low cloud cover, Ejército del Aire had a very, very nice Madrid flyover. It is sad to see Harriers slowly becoming history, but I feel really lucky to have seen some flying before they finally go.

The Westland Welkin was a high altitude fighter that entered production, but not service. The high altitude bomber threat disappeared and more mainstream types like the Spitfire and Mosquito grew to fill the niche, however…. 1/5

For years, I've been working towards building a website to house all of my opinions and research. Today, it goes live with the launch article: Jet Fighter Generations Aren't Real. This website comes with a major change in how I produce and share content, so please read. 🧵

One of the reasons for the rapid roll was the ease with which the pilot could apply the stick force. This was helped by an ingenious mechanism never seen before by the British. A counter weight rotated about a vertical axis and was geared to the aileron. Its motion under…. 5/7

One of the most instantly recognisable features of the spectacular, possibly Jules Verne-inspired HP Victor, was the exotic tailplane. This was ironic, because the Victor was the final result of a long series of tailless bomber concepts explored by the company. 1/10

How the Turbo-Ramjet engine works in one of France's finest follies, the Nord 1500 ‘Griffon II’. It was a prototype fighter capable of reaching Mach 2. Although it set European and world speed records, the Mirage III was preferred.

I will never not regret a bit, that I wasn't born in the mid-1930s US, just in time to hallucinate things like this.

I find it quite funny that the statement 'fighter aircraft usually have a wingspan of around 10 m' has remained continuously valid from WWI until now. I don't think there's anything deeper about it, but it is interesting.

So what DID we learn in Vietnam? First, slow planes were lost in far greater numbers than fast ones. A-1 Skyraiders were shot down at incredibly high rates when compared to even F-100s over Vietnam. (Ignore the F-105 in "overall"--most of its missions were over North Vietnam)
The more you learn about the expected role of the USAF tactical aviation in the Cold War around the A-10's inception, and what Vietnam taught the US, as well as Soviet doctrine and composition, the more you learn to love the A-10.

Predicted synoptic situation seems to be messed up over Europe rn, isobars are tightly packed... This will likely be a wild race with dramatic comebacks! I highly recommend checking the balloon tracker at https://t.co/mxjwt3jgKu, it is really thrilling. https://t.co/CxVlW6LYwk
🧭 North, south, east or west, nobody knows yet where the gas balloons of the #gordonbennett2024 will land. 🎈 The teams will use the meteorological activity 🌬️ to navigate within the defined competition area to reach the furthest distance from Münster 🏆 #aviation #gb2024

The RIM-8J was the last of the Talos missiles, and by far the best. With a range of up to 130nmi and a 465 pound warhead, the last model of Unified Talos could claim to be amongst the most lethal surface-to-air missiles of the Cold War, thanks in part to its Fire control System🧵

Strange fighter from the Great War with no wire bracing:
1/20 Some time ago, I stumbled upon an image of a small sesquiplane designed by Glenn Curtiss called the S-2 Wireless. If you carefully look at the photo, you will notice the ducted prop spinner and the elegant interplane bracing with no wires. Lets talk about this bracing!

As a post scriptum, if you wanted one more Curtiss thread, you can read about floating ailerons on Curtiss Tanager here.
1/30 The plane in the picture is the Curtiss Tanager, a neat safety-oriented machine by T.P. Wright and his team. The Tanager is too big of a topic for one thread, so we will limit ourselves to its peculiar floating-tip ailerons. Let's have a look at them!
