The island of Hawaii is built from five separate shield volcanoes that erupted somewhat sequentially, one overlapping the other. These volcanoes are: Kīlauea, Mauna Loa, Hualālai, Mauna Kea and Kohala.

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's erupting Kilauea volcano has now claimed more than 70 homes, and belched tens of thousands of tonnes of ash and noxious fumes into the air. (Click to subscribe for more Channel 4 News videos. https://www.youtube.com/channel4news?sub_confirmation=1) Every night, it puts on a spectacular - and terrifying - show with powerful fountains of lava lighting up the sky. Our Washington Correspondent Kylie Morris has spent the week on Big Island. After weeks of eruptions and lava flows from the Kilauea volcano in Hawaii there are increased worries about the health threats from Volcanic Smog and 'laze' which are thick hazardous clouds containing hydrochloric acid and glass particles. Kilauea on Hawaii's big island began eruptions at the beginning of the month. Scientists believe that the lava that has been flowing in a Hawaii residential neighbourhood since last week is magma that's been stored in the ground since the volcano erupted in the same area 63 years ago. Hawaii's business community has stressed that many tourist activities remain open, as do the island's airports.
June 9, 2018: The water off of the coast of Hawaii where the most recent lava flow is entering is now showing what appears to be a couple of huge circular boiling patterns. Could be a side effect of the lava but according to google earth the water is very deep in this particular area. Its several hundred yards off shore.

Your Washington, D.C. tour should start at the National Mall, where you’ll find monuments, memorials, and government buildings instead of tons of shopping. If you’d like to get around town easily but don’t want to rent a car, the Capital Bikeshare program will let you cruise around the city without wasting gas or getting stuck in traffic. Check out the Watergate Hotel and Kennedy Center when you stop at Foggy Bottom, then move on to Georgetown, the oldest district in D.C. It’s filled with 18th-century buildings and, of course, the university itself. After a stop at the National Cathedral, make your way to the Smithsonian National Zoo, the perfect stop for the young and the young at heart. If you’re feeling the need to channel your inner 007, go to the International Spy Museum, and learn about the covert operations and intelligence agencies that have shaped the world we live in.
