we danced with this big rascal in this thread before, back in #318 and #1,242 for example.

Gone (built 1969, retired 1991, scrapped 1999) and likely never to be seen again ("strip mining" has gone out of favor in most countries, on the scale at least needing a machine this gigantic would ever be made again, $775 million in today's money).

Only the bucket remains. Big Muskie Bucket

I read another interesting post on Facebook.

I guess I have an affinity with the F-4. Ever since the Blue Angels rocked the grandstands at an air show that I was at back in 1972, I believe.
I got a revisit of the F-4S at Point Mugu when I was working there on the F-14…

————————————————————

Why were the wings of the F-4 Phantom bent up and the tail of the Phantom bent down?

The unique design of the F-4 Phantom, with its wings, bent upwards and its tail bent downwards, was a result of meticulous engineering aimed at addressing specific aerodynamic challenges. The upward bend of the wings, known as dihedral, and the downward bend of the tail, known as anhedral, were crucial for enhancing the aircraft's stability and control at high speeds.

The dihedral angle of the wings, which is the upward tilt, was introduced to improve the lateral stability of the aircraft. During the development of the F-4, wind tunnel tests revealed that the aircraft experienced lateral instability at speeds above Mach 2. This instability could cause the aircraft to roll uncontrollably, which would be dangerous during high-speed flight. By angling the outer portions of the wings upwards by 12 degrees, the engineers were able to counteract this tendency, ensuring that the F-4 remained stable and controllable even at supersonic speeds.

On the other hand, the anhedral angle of the tailplane, which is the downward tilt, was designed to enhance the aircraft's maneuverability. The F-4 Phantom was a large and heavy aircraft, and without the anhedral tail, it would have been less responsive to pilot inputs, particularly during combat maneuvers. The 23-degree anhedral angle of the tailplane helped to improve the aircraft's roll rate and overall agility, making it more effective in dogfights and other dynamic flight situations.

The distinctive "dogtooth" indentation on the wings was another design feature aimed at improving control at higher angles of attack. This feature helped to delay the onset of aerodynamic stall, allowing the F-4 to maintain better control during aggressive maneuvers.

The only occasion that all four Iowa-class battleships were photographed operating together.

USS Iowa (BB-61). The others are (from near to far): USS Wisconsin (BB-64); USS Missouri (BB-63) and USS New Jersey (BB-62), 7 June 1954

Interesting. "Big rigs" of the sky. Notice something though.

The Antonov (casualty of Ukraine/Russia war. so its gone :() and the Boeing are older designs with six and four engines, respectively. The Airbus, a relatively newer design, gets the job done with only TWO engines.

Their cargo space/lifting capacity vary, but all three have/had relatively comparable heavy lift abilty, while the Airbus must have benefited from advancements in engine/materials development vs. the other two.

Western Mining History

September 25 at 1:30 PM ·

This massive Cornish pump was installed at the Ontario mine at Park City, Utah starting in late 1881. It took thirty Union Pacific freight cars to transport the parts to the mine. Some of the castings weighed ten tons. Assembling the pump at the mine took nearly two years, and was completed late in 1883. A USGS report described the pump:

The flywheel was 30 feet in diameter and weighed 70 tons. The pumps were 20 inches in diameter, had a 10-foot stroke, and were capable of throwing 320 gallons of water at each stroke. The pump rod, of Oregon pine, was 1,060 feet long and 16 inches square, and its several sections were united by iron strapping plates 1 by 10 and 1 by 12 inches 30 feet long, The pump lifted 2,560 gallons a minute, 153,600 gallons an hour, or 3,686,400 gallons a day from the 1,000-foot level to the drain tunnel on the 600-foot level.
