Lots and lots of beautiful P-51s, Bs and Ds. But there's also a special treat in there. An extremely rare P-51H!
First a gorgeous Mosquito. And suddenly, at 0:09, a rare Fairy Firefly passes by. Then, at 2:24, the P-51 Mustangs start to take off.
The P-51H doesn't take off. It comes from the outside. You see it first flying at 4:10. It emerges at 5:20 again, and lands at 6:38. At 9:00 there are some B-25s. Then at 9:38 another rarity, a B-29 Superfortress.
For those of you who don't know what a P-51H is: It's the fastest piston engined aircraft that saw service in WW2. It didn't fly in Europe, only in the Pacific region. It never engaged in combat, it was too late for that. It was like 60 Mph faster than the P-51B and P-51D, so it sure could move. It's not a direct modification of the previous Mustang versions. They remade it from the ground up. Its structure is lighter, its streamlining is even further refined, and it has a more powerful version of the Packard Merlin engine, specifically developed by Packard, not Rolls Royce. (The fastest piston engined aircraft to see combat during WW2 is the Republic P-47M Thunderbolt. The fastest piston engined aircraft to fly during WW2 was the XP-47J. I'm saying this because there are lots of people around who think that those titles belong to various German aircraft. That is not so.)

There is currently a flying P-82. The P-82 Twin Mustang was an ultra-long-range escort fighter that never made it into service during WW2, but flew in the Korean war.
This is not exactly just two bolted together Mustangs. The fuselages are pretty much new designs (lengthened XP-51F fuselages). The engines were not Packard Merlins on the service versions. This is called XP-82 so probably does have Merlins though (The prototype, XP-82 did). The two-staged supercharger Allison engine was a kind of rushed affair, not as competently designed as the Merlin's supercharger. This led to troubled service.

Out of the blue, YouTube suggestions dropped this surprise on me. Surprise because it's a very rare aircraft. Well, "rare", I suppose not true because i think they built a hefty number of these. But rarely seen, let's say. I had no idea one of these were still in flying condition. Anyway, it's so interesting I had to torture you with posting this video.
This is one of the fastest of the Mach 2 cold war interceptors. SAAB Draken, developed and built by a small nation, Sweden. By fast, I don't mean maximum speed at best altitude. I mean it "could move". During normal service, mission and combat flying. It was "fast" at all altitudes and it could keep it up. This is the ultimate version, the "J" model, and it set a world record for 1000 km closed circuit. And that record was set, not intentionally by a specially tuned, lightened, faired and polished, dedicated record setter with water injection etc, but accidentally by a pair of normal service fighters, on a navigation exercise. Also remarkable is that it was in service for 50 years. It dates back to the 1950s.

Vid on the first ever jet vs jet engagement between a British Gloster Meteor and German V-1 cruise missile over the skies of Britain in '44. The guns on the Meteor malfunctioned, which lead to the pilot improvising a solution on how to down the missile...

One thing I miss about the Cold War is seeing military air craft flying over my small town. South of me is a National Guard base and in the upper peninsula was a former SAC base which was closed in the early 90s when the Cold War came to an end. I used to see Hueys, A10s, B-52, F16s and other craft fly by once in a while when I was young. Huey helicopters have their unique sound, you hear them way before you see them. And A10s have their unique sound as they fly past you. I didn't realize until I was older that those B-52s probably had nuclear bombs and they were "cocked".

"Forgotten bombers"? I'm not so sure about that, since it's rather more like "all the bombers". But it does include some obscure varieties. I particularly liked that it makes justice to the Martin Baltimore, one of the most important bombers of WW2 RAF (backbone of Africa and Sicily campaigns), despite that it seems like a black hole in most takes on aviation history. There're also esoterics like the Bombay and Wellesley.

All the things he says are correct. So his channel might be something. I wouldn't have expected that in a YouTube channel - not mentioning any names, but there are a lot of misunderstandings being "explained".
I wouldn't have put it in the exact same words as he does, and I would have been more careful about not misleading into thinking that the vortex is the normal way of the delta wing to generate lift, but he gets it right.
Besides practical benefits like light and stiff construction, and internal volume, the main mission of the delta wing is to take a large wing area to high speeds. That is how I would put it.
The large area is needed for generating lift for airfield performance and combat maneuvering. At high Cl (coefficient of lift) the delta wing is grotesquely inefficient and draggy, but don't worry about things we can't have, focus on what we can have. We get the lift and don't get the stall. The vortex helps attaching the airflow and generate lift at high AoAs, which would normally be post-stall. (The leading root extensions you see on aircraft like the F-5E, F-18, F-16, Mig 29, Su 27 have the same function). At high speeds, we operate at low Cl and low AoA, so we're slick and don't get all the drag from the inefficient configuration at high Cl then.
Artificial stabilization mean that we get rid of trim drag. To better understand why that is a big deal, "less trim drag" means that the trailing edge of the delta wing is aerodynamically configurated to give the wing more lift at lower AoA. Together with the fact that a large wing area don't need so high Cl to achieve demanded lift, the wing stays efficient through a greater envelope (than a stable delta wing).
On one hand, wing area always costs drag, but high aspect ratio (F-18, Su 27) isn't the only way to combat induced drag (appears at high lift). A low wing loading is also a method to reduce induced drag, because induced drag is proportional to Cl. That is how Gripen, Typhoon, Rafale stayed relevant in the era of sustained hi-Gs.
Ultimately though, what makes or breaks the delta wing, is the weight, volume and stealth in the compromise of the whole package, i.e. aircraft, because, strictly aerodynamically, more conventional wings are better (hence American and Russian preferences).

The British navy had a great and unlikely success with the Swordfish biplane during the WW II. So of course, after the war they figured this contraption would be totally okay. (And I think it was)

Here's a fighter dodging six missiles if you can make it out what is happening on screen It is something that the F-16 is very good at. So called "rate fighters" (F-16, F-15, F-22, Typhoon) generally are. In this case he has to trade a lot of altitude at some point, but the key attribute is the ability to sustain energy. The HUD view is very narrow, but there is one instant where you can see the exhaust trails from several missiles (probably from him having turned around, as the rocket engines burn out). Towards the end, he appears to have locked something and to have turned his gunsight on. I don't know, but he is maybe following a missing missile upwards to altitude again? He would maybe do that to stop the radar crews from locking yet another missile on him (he is in the line of sight to the missile), or even use the missile as decoy. Must be frustrating to be a Russian SAM designer. Their allies have fired thousands the last decades but no hit much, except for a couple of civilian airliners full of passengers.

The Convair Pogo. Old VTOL experiment. There was a Lockheed plane, Salmon, using the same technology.
In the days, it didn't work out. They had to have a large prop to get enough thrust, and turboprops didn't really have the performance they wanted then. But the bigger problem was that it was very difficult to land. Too difficult to be operationally reasonable. It also required the plane to fly to great height during the transition from flying to vertical position for landing. Then it was a long and slow process to descend to a controlled landing. It kinda defeated the purpose of vertical landing because for safety it required a bigger field for landing than a conventional plane.
But that was then. I'm not so sure a tail sitter won't be a good idea again some day. With modern computerized controls and synthetic vision, taking off and landing could become a breeze. Just watch SpaceX landing their first stages.

UH-1Ys and UH-60s working wildfires. The Venom (UH-1Y) is basically a reinforced Huey with the engines and rotor package from the AH-1Z, which means it has twice as much horsepower as the Huey and being almost comparable to the Blackhawk (UH-60).
