THIS IS THE WORLD'S FASTEST AND LARGEST MEGA BOMBER YOU HAVE NEVER SEEN The North American XB-70 Valkyrie was the largest and fastest bomber ever built by the United States, but the massive six-engine Mach 3.0-capable jet never entered production. Only one surviving prototype sits in a museum in Dayton, Ohio, even as the Boeing B-52 it was supposed to one day replace continues to soldier on. The idea behind the XB-70 originated in the 1950s when it was assumed ever-greater speeds and altitudes would enable American bombers to survive against Soviet air defenses unmolested on their way to delivering their doomsday payloads. At the time, the only effective defense against bombers were fighters and antiaircraft artillery. Even then, anti-aircraft guns were only marginally effective and interceptors were increasingly challenged by ever improving bomber performance. The North American Aviation XB-70 Valkyrie was the prototype version of the planned B-70 nuclear-armed, strategic bomber for the United States Air Force Strategic Air Command. In the late 1950s, North American Aviation designed the Valkyrie as a large, six-engine bomber capable of reaching Mach 3+ while flying at 70,000 feet (21,000 m). At these speeds, it was expected that the B-70 would be almost immune to interceptor aircraft, the only effective weapon against bomber aircraft at the time. The bomber would spend only a few minutes over a particular radar station, flying out of its range before the controllers could position their fighters in a suitable location for an interception. High speed also made the aircraft difficult to see on the radar displays and its high-altitude flight could not be matched by any contemporary Soviet fighter. The introduction of the first Soviet surface-to-air missiles in the late 1950s put the near-invulnerability of the B-70 in doubt. In response, the United States Air Force (USAF) began flying its missions at low level, where the missile radar's line of sight was limited by local terrain. In this low-level role, the B-70 offered little additional performance over the B-52 it was meant to replace being far more expensive with shorter range. Other alternate missions were proposed, but these were of limited scope. With the advent of intercontinental ballistic missiles (ICBMs) during the late 1950s, manned bombers were increasingly seen as obsolete. The USAF eventually gave up fighting for its production and the B-70 program was canceled in 1961. Development was then turned over to a research program to study the effects of long-duration high-speed flight. As such, two prototype aircraft, designated XB-70A, were built; these aircraft were used for supersonic test-flights during 1964–69. In 1966, one prototype crashed after colliding in mid-air with a smaller jet aircraft; the remaining Valkyrie bomber is in the National Museum of the United States Air Force near Dayton, Ohio.

Hawaii Kilauea Volcano Update: USGS Map, Lava Flows Continue

Hawaii Kilauea Volcano Update: USGS Map, Lava Flows Continue The volcano has destroyed everything in its path since the initial eruption and showed no signs of slowing down more than two months into its activity. Homes, roads and parking lots have been covered in lava or have fallen into the volcano’s caldera. Collapse events at the summit continued to cause what feels like earthquakes across the island for those in the area, plaguing residents for weeks on end. Seismicity drops just after such a collapse, but picks back up again a few hours later, building until another collapse event occurs. The most recent collapse event happened Sunday, according to the United States Geological Survey. The summit of the volcano was still releasing sulfur dioxide, though levels have dropped as the activity has continued. Gas and the ash coming from the volcano can cause irritation to the skin, eyes and lungs—and both were traveling downwind of the summit.
