That is the thing, twoofers who tell these stories tend to leave out important details. How long was the B52 flying at that speed before it disintegrated? Nobody doubts that flying a Boeing 757 at that speed at that altitude is not a good idea for anyone with long term plans for the future of themselves or the plane.
But it tells us nothing about accelerating to reach that speed or diving to maintain that speed a few seconds before a deliberate crash.
Well then, its time to bring some actual truth to the utter bollocks and lies Fonebone is getting from his bull-**** source, and posting here, about this June 1959 B-52 crash and how it is irrelevant to anything that happened on 9/11.

"The bomber was scheduled to fly at lower than 500 feet above the ground on an elliptical course from The Dalles, Oregon, to Malheur Lake, Burns, and back to Walla Walla, Washington, at near maximum speed of 638 miles-per-hour. The Strategic Air Command (SAC) needed to know if the giant Stratofortress, specifically designed to fly at high altitudes, could survive the secondary structural stresses caused by violent air turbulence found at very low altitudes. The flights were being conducted to determine the feasibility of flying the world’s largest bomber under enemy radar warning systems to deliver a nuclear payload. It was during the height of the Cold War (1946-1991) and the intended target would be the Soviet Union (USSR).
At 11:30 a.m., Tommy’s Tigator radioed that it was over The Dalles and preparing to descend for the low-level test flight. No further reports were heard from the pilot after it passed the checkpoint. Leslie Heinz, a lineman for the Harney County Rural Electric Cooperative, was an eyewitness to the accident. He was working with a crew on power lines in a remote area approximately 35 miles west of Burns and three miles from the crash site. At about 12:00 noon, he spotted the B-52 flying southeast approximately 300 feet above the desert floor when it suddenly crashed. Said Heinz: "
The claim: The B-52 disintegrated at 300 ft,
400 kn
The facts: The B52 crashed when its horizontal stabiliser suffered structural failure at 636 mph
(554 kn) and as a result, the aircraft pitched up, stalled and and crashed into a sandy knoll. The aerodynamic stress on the B52 airframe would have been about 20% higher at that speed than at the claimed 400 kn.
Its worth noting that these B-52 low-level high-speed bomb run tests began in 1955 (they had previously been carried out with its predecessor, the B-47), and in all that time, the 1959 crash was the only incident. Furthermore, Boeing modified and strengthened the B-52 horizontal stabilizer, and the low-level high-speed flight tests continued without further incident throughout the rest of 1959 and 1960, stopping only in mid 1961 after the US's first ICBM (the Atlas SM-65) became fully operational.
The claim: That the 9/11 airliners could not have gone at the speed and altitude they did without disintegrating.
The facts: The B-52 was running at a sustained speed of 554 kn for almost 30 minutes before the horizontal stabilizer failure caused it crash. However...

Took off at 7:59, was hijacked at 8:14 and at 8:43, was still cruising at 10,000 feet before beginning a shallow dive at 3,200 ft/min, and less than three minutes later, reaching a maximum speed of 404 kn before crashing into the North Tower at 8:46

Took off at 8:14, was hijacked between 8:42 and 8:47, was still at 28,500 feet at 8:57 before beginning its shallow dive and less that six minutes later reaching a maximum speed of 430 kn before crashing into the South Tower at 8:46

Took off at 8:20, was hijacked between 8:51 and 8:57, was still at 25,250 feet at 9:22 and began to descend, to between 8000 and 6800 feet when it began a 330° descending turn to about 2,00 feet toward the Pentagon and 4 miles south-west. The aircraft then pitches down and accelerates to about 460 kn over the next 30 seconds into impact at 9:37.
In all three cases, the airliners' maximum speeds were far lower than that of the B-52, and were sustained for a much, much shorter time. Since the aircraft were
accelerating towards their targets, they would have maintained their peak velocities for only a few seconds prior to impact - nowhere near enough time for the aerodynamic stresses on them to lead to any kind of structural failure.
