1958 Tybee Island Mid-air Collision
The Tybee Island mid-air collision was an incident on February 5, 1958, in which the United States Air Force lost a Mark 15 nuclear bomb in the waters of Tybee Island near Savannah, Georgia, United States. During a night practice exercise, an F-86 fighter plane collided with the B-47 bomber carrying the large weapon. The bomb was jettisoned to help prevent a crash and explosion. After several unsuccessful searches, the weapon was declared lost in Wassaw Sound off the shores of Tybee Island. Collision The B-47 bomber was on a simulated combat mission from Homestead Air Force Base in Florida, carrying a single bomb. At about 2:00 a.m. EST ''(UTC−5)'', an F-86 fighter collided with the six-engine B-47. The F-86 pilot, Lt. Clarence Stewart, ejected and parachuted to safety near Estill, South Carolina, north of the fighter's crash site east of Sylvania, Georgia. The damaged B-47 remained airborne, plummeting from until the pilot, Col. Howard Richardson, regain ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mark 15 Nuclear Bomb
The Mark 15 nuclear bomb, or Mk-15, was a 1950s American thermonuclear bomb, the first relatively lightweight () thermonuclear bomb created by the United States. A total of 1,200 Mark 15 bombs were produced from 1955 to 1957. There were three production variants: Mod 1, Mod 2, and Mod 3. The design was in service from 1955 to 1965. Specifications All three models were generally physically similar; weight of around , diameter of , length of . Models The Mod 1 corresponds to the Castle Nectar test of the Zombie weapon prototype. This test had a yield of . The Mod 2 corresponds to the Redwing Cherokee nuclear test of the TX-15-X1 test model, and had a yield of . Redwing Cherokee was the first US thermonuclear bomb airdrop test. a [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Coordinated Universal Time
Coordinated Universal Time (UTC) is the primary time standard globally used to regulate clocks and time. It establishes a reference for the current time, forming the basis for civil time and time zones. UTC facilitates international communication, navigation, scientific research, and commerce. UTC has been widely embraced by most countries and is the effective successor to Greenwich Mean Time (GMT) in everyday usage and common applications. In specialised domains such as scientific research, navigation, and timekeeping, other standards such as Universal Time, UT1 and International Atomic Time (TAI) are also used alongside UTC. UTC is based on TAI (International Atomic Time, abbreviated from its French name, ''temps atomique international''), which is a weighted average of hundreds of atomic clocks worldwide. UTC is within about one second of mean solar time at 0° longitude, the currently used prime meridian, and is not adjusted for daylight saving time. The coordination of t ...

Plutonium
Plutonium is a chemical element; it has symbol Pu and atomic number 94. It is a silvery-gray actinide metal that tarnishes when exposed to air, and forms a dull coating when oxidized. The element normally exhibits six allotropes and four oxidation states. It reacts with carbon, halogens, nitrogen, silicon, and hydrogen. When exposed to moist air, it forms oxides and hydrides that can expand the sample up to 70% in volume, which in turn flake off as a powder that is pyrophoric. It is radioactive and can accumulate in bones, which makes the handling of plutonium dangerous. Plutonium was first synthesized and isolated in late 1940 and early 1941, by deuteron bombardment of uranium-238 in the cyclotron at the University of California, Berkeley. First, neptunium-238 (half-life 2.1 days) was synthesized, which then beta-decayed to form the new element with atomic number 94 and atomic weight 238 (half-life 88 years). Since uranium had been named after the planet Uranus ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Emergency Landing
An emergency landing is a premature landing made by an aircraft in response to an emergency involving an imminent or ongoing threat to the safety and operation of the aircraft, or involving a sudden need for a passenger or crew on board to terminate the flight (such as a medical emergency). It typically involves a forced diversion to the nearest or most suitable airport or airbase, or an forced landing, off airport landing or ditching if the flight cannot reach an airfield. Flights under air traffic control will be given priority over all other aircraft operations upon the declaration of the emergency. Types There are several different types of emergency landings for powered aircraft: planned landing or unplanned landing. * ''Forced landing'' – the aircraft is forced to make a landing due to technical problems. Landing as soon as possible is a priority, no matter where, since a major system failure has occurred or is imminent. It is caused by the failure of or damage to vital ...

Spokane Daily Chronicle
The ''Spokane Daily Chronicle'' is a daily digital newspaper in Spokane, Washington. It was founded as a weekly paper in 1881 and grew into an afternoon daily, competing with ''The Spokesman-Review'', which was formed from the merger of two competing papers. History In 1897, the ''Chronicle'' was acquired by William H. Cowles and became part of the Cowles Company, Cowles Publishing Company. Cowles already owned ''The Spokesman-Review''. Both papers operated out of the Review Building until 1921, but were kept independent; ''The Spokesman-Review'' had a Republican political slant, and the two papers maintained a friendly rivalry. The ''Chronicle'' moved into its own building next door in 1921. The following year the ''Chronicle'' started radio station KOE, setting up an antenna on the taller ''Review'' building. The station operated for less than a year. A ''Chronicle'' Building was first planned in 1917. The final building that remains standing today was designed by G.A. Pehrs ...
