The "crab-leg" landing.
B-52's never had this issue because of the crosswind crab system for crosswind landings
I never got tired watching them test this as they taxied after I launched one

Amazing aircraft. I've never seen one up close, but when I was a kid living in middle of nowhere southern Tier New York, it was fun watching the planes fly over, as we were near a VOR. B52 was easy to identify by the 8 contrails.
i'll be dammed. Starting about 2:10 till the end a couple mins. later.
now that;s a "crabwalk" ... hundreds of feet it looks like, ALL wheels down, slowing (brakes, chute, full flaps, etc.) the whole time, then "steering(?)" out of it to correct the starboard yaw. That's the way it looked to me
here's the real story: swiveling landing gear, unique among all aircraft. engineered in.. source: Watch This B-52 'Crabwalk' Down The Runway In A Heavy Crosswind
"Because of the B-52’s massive side surface area and low-slung wing, crosswind landings are especially challenging. With this issue in mind, Boeing engineers built the B-52’s main tandem landing gear with a genius feature — they swivel. The details of this feature were kept secret for years after the Stratofortress’s introduction into service.
The pilot simply dials in the runway’s heading via a rotary dial in the cockpit and the gear will remain properly aligned with a selected compass heading throughout the jet’s approach. This way the pilot can fly the approach crabbed into the wind, with its wings level, all the way down to touchdown and rollout.
This capability is especially relevant as the B-52’s wingtips and outrigger landing gear are far from the fuselage’s centerline and hang nearly as low as the jet’s lower fuselage edge. Just a couple of degrees of roll to the left or to the right could result in a wing dipping multiple feet. As a result, using ailerons to sideslip or even de-crab the jet before touchdown could end in a wing-strike catastrophe.
Thus B-52 pilots fly intensely crabbed crosswind approaches, sometimes looking out the cockpit’s side windows at the runway, all the way through touchdown and rollout."

The Six-Engine B-29: America’s Secret Superbomber
Recently declassified documents reveal a little-known World War II project: a six-engine B-29 variant, the "XB-29T Super Superfortress." This bomber was designed for direct strategic bombing missions from the U.S. mainland, eliminating the need for vulnerable Pacific island bases.
By late 1944, military planners sought ultra-long-range capabilities. Boeing proposed adding two extra Wright R-3350 engines to a stretched B-29, increasing thrust, range, and bomb load. The design included:
Six engines generating 18,000 horsepower
Extended fuselage for added fuel
Projected non-stop missions to Japan with aerial refueling
Wind tunnel tests revealed aerodynamic and fuel consumption challenges. With Japan’s surrender in 1945, the project was scrapped. The test airframe was dismantled, and official records remained classified for decades.
Some believe the XB-29T influenced Cold War bombers like the B-36, while others see it as an ambitious yet impractical experiment. Regardless, this secret bomber remains an April Fool's post
Sorry about the day late post ;^)

Me262 HG III V Tail,
In April 1941, Adolf Busemann proposed fitting a 35° swept wing to the Me 262, sparking the Hochgeschwindigkeit ("high-speed") project. In 1944, the Me 262 HG I featured a low-profile canopy. The HG II proposed a 35° swept wing, closer-mounted engines, and a V-tail, though testing reverted it to a conventional tail. The HG III was planned with a 45° swept wing and Heinkel HeS 011 engines but remained unbuilt.
Never built but would have been interesting.

This beast was visiting Finland for a couple of summers. Parola Armored Museum. Finland.
One of The Tank Museum's two Tiger IIs before it was repainted into a more accurate color. This particular example is actually an early Tiger II prototype, the second built, known as the V2 prototype. You will notice the curved turret - this is not a "Porsche" turret as is often believed. Both this turret and the Tiger II's more common, flat-fronted turret were both made by Krupp.

Happy 73rd birthday to the BUFF!!
April 15th, 1952; the mighty B-52 Stratofortress took to the skies on her very first flight.
The B-52, also known as the BUFF (Big Ugly Fat F..ker), America’s 8-engine strategic jet bomber, will now undergo extensive modifications to keep them flying for at least 30 more years. If realized, she will have been patrolling the skies for 90 years, an impressive feat for any aircraft, but especially for 1950s-era strategic nuclear weapon capable bombers that were supposed to be replaced by the B-1, then the B-2 Spirit, only to outlive both her replacements.
The BUFF’s incredible lifespan would be the equivalent of a World War I Bi-plane remaining fully operational and in continual military service until the year 2004.
First flown in 52, the B-52 has been in continuous service, undergoing multiple and extensive upgrades during its lifetime. The B-52 is expected to serve up to stardate 53000.0 and beyond if no suitable replacement is available at that time.

On this date (Mar. 30) in 1964, a contract for production of 76 F-1 engines was awarded by the Marshall Space Flight Center to Rocketdyne (valued at $158.4 million) for the production of 76 F-1 engines for the first stage of the Saturn V launch vehicle and for delivery of ground support equipment.
The F-1 was the largest liquid-propellant rocket engine ever built; five propelled the first stage of the Saturn V. Each F-1 could be gimbaled (swiveled), was about as big as a two-and-a-half-ton truck, developed 6.7 million newtons of thrust at sea level (as much as all three Space Shuttle Main Engines combined), and burned three tons of liquid oxygen and RP-1 (kerosene mixture) propellants every second. RP-1 served not only as the fuel for the engine but also as the turbopump lubricant and the control system fluid. A gas generator utilizing the same propellants drove the turbine, which was directly coupled to the turbopump.
This photograph shows F-1 engines being stored in the F-1 Engine Preparation Shop, Building 4666, at the Marshall Space Flight Center.

B-52's are/were an extraordinary design. still in professional (military) usage potentially now for a century (into 2050+) is remarkable.
diggin the trek tech ... i didnt think Constitution-class ( Jim Kirk's first Enterprise) made it to 2300 still in service?

I was young, but I remember this test. 1.5M pounds of thrust, each engine.
i did a book report on it like a couple years later, when science teacher asked me (for extra credit) why didnt it take off during test. i thought it was a trick question, but it was friggin' fascinating (and completely obvious later). Not only was it bolted to the stand, the stand had to weigh more than 7.5M lbs (assuming attachments were strong enough).
IIRC, that weight in concrete alone was like 14M lbs, plus the structural steel, plus rocket Ist stage itself --- so maybe 18M lbs. it wasnt going anywhere.
Anyway, eight minutes of footage. Remarkable slide-rule engineering of EVERYTHING in this video.
If anyone wants to nerd out on the FI, here's 25 minutes of "pocket protector" heaven in a tutorial with graphics.

That’s
neat.
If I remember correctly, they had to get the old sketches and notes from the engineers that made the F-1s when they were designing the Artemis engine. Many of the original engineers had passed away.

plus, those dudes (engineers) were old anyway -- In their 60's in the 1960's
Rocketdyne got the development contract in like 1953 to design 1M lb thrust rocket engine ... cuz Werner Von Braun told them it would take multiples of that much power to get to the moon.
good thing we stole (actually he defected with like 1,000 other ex nazi V1/V2 rocketeers after the war) him from the Nazis.
had that war gone differently, the world we live/grew up in (another topic) woulda be much different.

Originally the Olds 75mm cannon was hand loaded, which allowed for three or four shots per minute. Later, an automatic feed system was developed that utilized the T9E1 75mm cannon with an automatic feed system, which was not produced by Oldsmobile.
These airborne artillery units possessed the capability to obliterate enemy aircraft (an occurrence documented at least once) and swiftly incapacitate Japanese vessels with precise targeting.
Admittedly, each discharge apparently resulted in a reduction of 40mph in airspeed, but considering the formidable 3-inch diameter of the artillery shell being deployed, the trade-off seemed reasonable.

The ME 163 S or Habicht (Hawk) was a glider trainer version of the ME 163 rocket plane. The glider differed from the production model by the addition of an instructor’s cockpit and the removal of the rocket engine. It seems only one was built. This was built by converting an earlier Me 163B-1 model.
