LTV A-7 Corsair II
The LTV A-7 Corsair II is an American carrier-capable subsonic light attack aircraft designed and manufactured by Ling-Temco-Vought (LTV). The A-7 was developed during the early 1960s as replacement for the Douglas A-4 Skyhawk. Its design was derived from the Vought F-8 Crusader; in comparison with the F-8, the A-7 is both smaller and restricted to subsonic speeds, its airframe being simpler and cheaper to produce. Following a competitive bid by Vought in response to the United States Navy's (USN) ''VAL'' (Heavier-than-air, Attack, Light) requirement, an initial contract for the type was issued on 8 February 1964. Development was rapid, first flying on 26 September 1965 and entering squadron service with the USN on 1 February 1967; by the end of that year, A-7s were being deployed overseas for the Vietnam War. Initially adopted by USN, the A-7 proved attractive to other services, soon being adopted by the United States Air Force (USAF) and the Air National Guard (ANG) to repl ...

Maryland Route 7
Maryland Route 7 (MD 7) is a collection of state highways in the U.S. state of Maryland. Known for much of their length as Philadelphia Road, there are five disjoint mainline sections of the highway totaling that parallel U.S. Route 40 (US 40) in Baltimore, Harford, and Cecil counties in northeastern Maryland. The longest section of MD 7 begins at US 40 just east of the city of Baltimore in Rosedale and extends through eastern Baltimore County and southern Harford County to US 40 in Aberdeen. The next segment of the state highway is a C-shaped route through Havre de Grace on the west bank of the Susquehanna River. The third mainline section of MD 7 begins in Perryville on the east bank of the Susquehanna River and ends at US 40 a short distance west of the start of the fourth section, which passes through Charlestown and North East before ending at US 40, just west of Elkton. The fifth segment of the highway begin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Benzanthrone
Benzanthrone (BZA) is a polycyclic aromatic hydrocarbon. It is a yellow solid. Its derivatives are used as a dyestuff intermediate for anthraquinone-based dyes. Dehydrogenative coupling gives violanthrone. It is prepared by reduction of anthroquinone to anthrone followed by alkylation with a mixture of glycerol and sulfuric acid. It is a basic substance with fluorescent and luminescent properties. It can be used for photosensitization, and as a charge transport material. It is also used in pyrotechnics industry, mainly as a component of some older formulations of green and yellow colored smokes, often together with Vat Yellow 4; its US military specification is MIL-D-50074D. Safety Benzanthrone causes itching and burning sensations on exposed skin, together with erythema, dermatitis Dermatitis is inflammation of the skin, typically characterized by itchiness, redness and a rash. In cases of short duration, there may be small blisters, while in long-term cases the skin ma ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
SET 7
__NOTOC__ The SET 7 was a military trainer and reconnaissance aircraft that was produced in Romania in the mid-1930s. It was originally designed as a conventional single-bay biplane, with slightly staggered wings, a standard undercarriage with fixed tailskid, and a tandem open-cockpit arrangement for the pilot and instructor or observer. Power was supplied by an Armstrong Siddeley Jaguar radial engine, and from the outset the aircraft was equipped for wireless and photographic reconnaissance duties. An armed version followed in 1934, adding a trainable machine gun for the observer and a fixed machine gun for the pilot. This version, the 7K, was powered by a neatly cowled Gnome-Rhône 7Ksd engine, and the 7KB (fitted with bomb racks) and 7KD were specialised subtypes that followed it. A floatplane version was produced as the 7H. Variants *SET 7 - initial unarmed trainer version with Armstrong Siddeley Jaguar engine (50 built, 1932–1934) *SET 7K - armed reconnaissance version wi ...

Era Alaska
Northern Pacific Airways, Inc., d.b.a. Ravn Alaska, is an Alaskan airline that specializes in serving the small communities in the US state of Alaska. The airline is headquartered in Anchorage, which is also home to its primary hub, Ted Stevens Anchorage International Airport. Ravn Alaska currently serves 12 communities in Alaska. Northern Pacific operates all of its flights using the Ravn Alaska brand. The company pronounces its name Ravn like the bird, Raven. Ravn has a partnership with Alaska Airlines, allowing passengers to book interlining flights and allowing passengers on most Ravn flights to earn miles in Alaska's Mileage Plan frequent-flyer program. History Northern Pacific traces its roots to June 20, 1948, and the founding of Economy Helicopters. The company was founded by Carl Brady; he flew the first commercial helicopter to Alaska to work on a mapping contract for the U.S. government. In the years that followed, Economy Helicopters renamed itself Era He ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Remembrance Of The Daleks
''Remembrance of the Daleks'' is the first serial of the 25th season of the British science fiction television series ''Doctor Who''. The serial was first broadcast in four weekly episodes from 5 to 26 October 1988. It was written by Ben Aaronovitch and directed by Andrew Morgan. In the serial, alien time traveller the Doctor (Sylvester McCoy) and his companion Ace (Sophie Aldred) travel back to 1963 to retrieve the Hand of Omega, a powerful device created by the Doctor's Time Lord race, and keep it from the Daleks. The serial contains many references to the history of the show, featuring settings from the first ''Doctor Who'' episode, ''An Unearthly Child'', such as Coal Hill School and the junkyard at 76 Totter's Lane. In reader polls conducted by ''Doctor Who Magazine'' from 1998 onwards, ''Remembrance of the Daleks'' has consistently been voted as one of the greatest ''Doctor Who'' stories of all time. The serial is the final appearance of the Daleks in the original run. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Hydrogen-7
Hydrogen (1H) has three naturally occurring Isotope, isotopes, sometimes denoted , , and . and are stable, while has a half-life of years. Heavier isotopes also exist, all of which are synthetic and have a half-life of less than one Orders of magnitude (time)#Zeptosecond, zeptosecond (10−21 s). Of these, is the least stable, while is the most. Hydrogen is the only chemical element, element whose isotopes have different names that remain in common use today: the (or hydrogen-2) isotope is deuterium and the (or hydrogen-3) isotope is tritium. The symbols D and T are sometimes used for deuterium and tritium. The International Union of Pure and Applied Chemistry, IUPAC accepts the D and T symbols, but recommends using standard isotopic symbols ( and ) instead to avoid confusion in the alphabetic sorting of Chemical formula, chemical formulas. The isotope , with no Neutron, neutrons, is sometimes called Hydrogen atom, protium. (During the early study of radioactivity, ...
