1966 Palomares B-52 Crash
The Palomares incident occurred on 17 January 1966, when a United States Air Force Boeing B-52 Stratofortress#Variants, B-52G bomber collided with a Boeing KC-135 Stratotanker, KC-135 tanker during Aerial refueling, mid-air refueling at over the Mediterranean Sea, near the Spanish village of Palomares, Almería, Palomares in Province of Almería, Almería province. The collision destroyed the tanker, killing all four crew members, and caused the bomber to break apart, resulting in the deaths of three of its seven crew members. The B-52G was participating in Operation Chrome Dome, a Cold War airborne alert mission involving continuous flights of nuclear-armed bombers. At the time of the accident, the B-52G was carrying four B28 nuclear bomb, B28FI Mod 2 Y1 Thermonuclear weapon, thermonuclear bombs. Three of these bombs fell on land near Palomares; the conventional explosives in two detonated upon impact, dispersing plutonium and Radioactive contamination, contaminating approxima ...

B28 Nuclear Bomb
The B28, originally Mark 28, was a thermonuclear weapon, thermonuclear bomb carried by United States, U.S. tactical fighter bombers, attack aircraft and bomber aircraft. From 1962 to 1972 under the NATO nuclear weapons sharing program, American B28s also equipped six Europe-based Canadian Canadair CF-104 Starfighter, CF-104 squadrons known as the RCAF Nuclear Strike Force. It was also supplied for delivery by UK-based Royal Air Force Vickers Valiant, Valiant and English Electric Canberra, Canberra aircraft assigned to NATO under the command of SACEUR. In addition, certain U.S. Navy carrier based attack aircraft such as the A-3 Skywarrior, A3D (later A-3B) Skywarrior, A-4 Skyhawk, A4D (later A-4) Skyhawk, and A-5 Vigilante, A3J (later A-5A) Vigilante were equipped to carry the B28. Production history Initial development of the IN and EX weapons During the design of the Mark 15 nuclear bomb, TX-15 in 1953 it became evident to designers that massive reductions in size and weight of ...

Longeron
In engineering, a longeron or stringer is a load-bearing component of a framework. The term is commonly used in connection with aircraft fuselages and automobile chassis. Longerons are used in conjunction with stringers to form structural frameworks. Aircraft In an aircraft fuselage, stringers are attached to formers (also called frames) and run in the longitudinal direction of the aircraft. They are primarily responsible for transferring the aerodynamic loads acting on the skin onto the frames and formers. In the wings or horizontal stabilizer, longerons run spanwise (from wing root to wing tip) and attach between the ribs. The primary function here also is to transfer the bending loads acting on the wings onto the ribs and spar. The terms "longeron" and "stringer" are sometimes used interchangeably. Historically, though, there is a subtle difference between the two terms. If the longitudinal members in a fuselage are few in number (usually 4 to 8) and run all along the ...

KC-135 Stratotanker Boom Operator
The Boeing KC-135 Stratotanker is an American military aerial refueling tanker aircraft that was developed from the Boeing 367-80 prototype, alongside the Boeing 707 airliner. It has a narrower fuselage and is shorter than the 707. Boeing gave the aircraft the internal designation of Model 717 (number later assigned to a different Boeing aircraft). The KC-135 was the United States Air Force (USAF)'s first jet-powered refueling tanker and replaced the KC-97 Stratofreighter. The KC-135 was initially tasked with refueling strategic bombers, but it was used extensively in the Vietnam War and later conflicts such as Operation Desert Storm to extend the range and endurance of US tactical fighters and bombers. The KC-135 entered service with the USAF in 1957; it is one of nine military fixed-wing aircraft (six American, three Russian) with over 60 years of continuous serviceThe nine military fixed-wing aircraft with over 60 years of continuous service are Boeing B-52 Stratofortress b ...

Mid-air Refueling
Aerial refueling ( en-us), or aerial refuelling (en-gb), also referred to as air refueling, in-flight refueling (IFR), air-to-air refueling (AAR), and tanking, is the process of transferring aviation fuel from one aircraft (the tanker) to another (the receiver) while both aircraft are in flight. The two main refueling systems are '' probe-and-drogue'', which is simpler to adapt to existing aircraft and the '' flying boom'', which offers faster fuel transfer, but requires a dedicated boom operator station. The procedure allows the receiving aircraft to remain airborne longer, extending its range or loiter time. A series of air refuelings can give range limited only by crew fatigue/physical needs and engineering factors such as engine oil consumption. Because the receiver aircraft is topped-off with extra fuel in the air, air refueling can allow a takeoff with a greater payload which could be weapons, cargo, or personnel: the maximum takeoff weight is maintained by carrying les ...

Pituffik Space Base
Pituffik Space Base ( ; ; ), formerly Thule Air Base (), is a United States Space Force base located on the northwest coast of Greenland in the Kingdom of Denmark under a defense agreement between Denmark and the United States. 150 United States guardians serve there, after the United States significantly reduced its presence from 6000 personnel during the Cold War. Denmark was a founding member of NATO in 1949, and the 1951 Greenland Defense Agreement allowed the United States to operate the base under a NATO framework, as long as both Denmark and the United States remain NATO members. Under the agreement, the Flag of Denmark, Danish national flag must be flown at the base to recognize that the base is on Danish territory, but the United States is allowed to fly its own flag alongside the Danish flag on the facilities it operates. It is the northernmost installation of the U.S. Armed Forces, north of the Arctic Circle and from the North Pole. Pituffik's Arctic environment in ...

1968 Thule Air Base B-52 Crash
On 21 January 1968, an aircraft accident, sometimes known as the Thule affair or Thule accident (; ), involving a United States Air Force (USAF) Boeing B-52 Stratofortress, B-52 bomber occurred near Thule Air Base in the Danish territory of Greenland. The aircraft was carrying four B28 nuclear bomb, B28FI thermonuclear bombs on a Cold War "Operation Chrome Dome, Chrome Dome" alert mission over Baffin Bay when a cabin fire forced the crew to abandon the aircraft before they could carry out an emergency landing at Thule Air Base. Six crew members ejected safely, but one who did not have an ejection seat was killed while trying to bail out. The bomber crashed onto sea ice in North Star Bay, Greenland, causing the conventional explosives aboard to detonate and the nuclear payload to rupture and disperse, resulting in radioactive contamination of the area. The United States and Denmark launched an intensive clean-up and recovery operation, but the Teller–Ulam design#Basic principle ...

Submersible
A submersible is an underwater vehicle which needs to be transported and supported by a larger ship, watercraft or dock, platform. This distinguishes submersibles from submarines, which are self-supporting and capable of prolonged independent operation at sea. There are many types of submersibles, including both human-occupied vehicles (HOVs) and uncrewed craft, variously known as remotely operated vehicles (ROVs) or unmanned underwater vehicles (UUVs). Submersibles have many uses including oceanography, underwater archaeology, ocean exploration, tourism, underwater work, equipment maintenance and underwater search and recovery, recovery and underwater videography. History The first recorded self-propelled underwater vessel was a small oar-powered submarine conceived by William Bourne (mathematician), William Bourne (c. 1535 – 1582) and designed and built by Dutch inventor Cornelis Drebbel in 1620, with two more improved versions built in the following four years.Konstam (201 ...
