21st Special Operations Squadron

The 21st Special Operations Squadron is a unit within the 352d Special Operations Group (352 SOG), United States Air Force, United States European Command, and was based at Royal Air Force base RAF Mildenhall in Suffolk, eastern England.

Mission

The 21st Special Operations Squadron, which fell under the 352nd Special Operations Group, RAF Mildenhall, UK, was inactivated on 31 October 2007 with the inactivation ceremony taking place at RAF Mildenhall, UK on 9 October temporarily ending the Air Force Special Operations vertical lift mission in Europe.

The inactivation of the Dust Devils was the first step in preparation for the arrival of the CV-22 tilt-rotor aircraft.

The 21st Special Operations Squadron's mission consisted of day or night, all-weather, low-level penetration of denied territory to provide infiltration, exfiltration, resupply, or fire support for elite air, ground, and naval forces. The unique capabilities of the MH-53J permitted the squadron to operate from unprepared landing zones.

8th Special Operations Squadron

The 8th Special Operations Squadron (8 SOS) is a squadron of the United States Air Force. It is assigned to the 1st Special Operations Wing, Air Force Special Operations Command, stationed at Hurlburt Field, Florida. The squadron is equipped with the CV-22 Osprey in support of special operations.

The 8 SOS is one of the oldest units in the United States Air Force, being organized as the 8th Aero Squadron on 21 June 1917 at Kelly Field, Texas. The squadron deployed to France and fought on the Western Front during World War I, equipped with United States-built Dayton-Wright DH-4, being used as reconnaissance aircraft.

During World War II, the squadron fought in the Southwest Pacific Area with Fifth Air Force as an attack and later B-25 Mitchell medium bomber squadron. During the Cold War, it fought in the Korean War with B-26 Invader medium bombers and Vietnam War as a B-57 Canberra medium bomber and later as an Air Commando squadron with A-37 Dragonfly counter-insurgency aircraft.

Apple SOS

The Sophisticated Operating System, or SOS /ˈsɔːs/, is the primary operating system developed for the Apple III computer. The system was developed by Apple Computer, Inc. and released in 1980. SOS makes the resources of the Apple III available in the form of a menu-driven utility program as well as a programming API.

The Apple III System Utilities program shipped with each Apple III computer. It provided what today would be called the end user "experience" of the operating system if the user were running it instead of an application program. The System Utilities program was menu-driven and performed tasks in three categories:

Technical details

SOS was a single-tasking operating system. A single program is loaded at boot time, called the interpreter. Once running, the interpreter could then use the SOS application programming interface to make requests of the system. The SOS API was divided into four main areas:

Reading (MBTA station)

Reading is a commuter rail station in Reading, Massachusetts, United States, on the Haverhill/Reading Line of the Massachusetts Bay Commuter Railroad, a branch of the Massachusetts Bay Transportation Authority (MBTA). It is located at Lincoln and High Streets on the western fringe of the town's central business district.

The station's historic depot building was built in 1870 to service the Boston and Maine Railroad and was the former terminus of the line before its extension to Haverhill. The MBTA purchased the Haverhill Line in 1973, intending to replace commuter rail service with extended Orange Line subway service between Oak Grove and Reading. This plan was rejected by riders who desired to retain commuter rail service. The second track was not rebuilt through the station when the outbound platform was built, so the inbound platform serves trains in both directions. Despite this limited capacity, Reading is the terminus for some local trains on the line.

Architecture and building history

Reading (process)

Reading is a complex cognitive process of decoding symbols in order to construct or derive meaning (reading comprehension). Reading is a means of language acquisition, of communication, and of sharing information and ideas. Like all languages, it is a complex interaction between the text and the reader which is shaped by the reader’s prior knowledge, experiences, attitude, and language community which is culturally and socially situated. The reading process requires continuous practice, development, and refinement. In addition, reading requires creativity and critical analysis. Consumers of literature make ventures with each piece, innately deviating from literal words to create images that make sense to them in the unfamiliar places the texts describe. Because reading is such a complex process, it cannot be controlled or restricted to one or two interpretations. There are no concrete laws in reading, but rather allows readers an escape to produce their own products introspectively. This promotes deep exploration of texts during interpretation. Readers use a variety of reading strategies to assist with decoding (to translate symbols into sounds or visual representations of speech) and comprehension. Readers may use context clues to identify the meaning of unknown words. Readers integrate the words they have read into their existing framework of knowledge or schema (schemata theory).
