The Family of Medium Tactical Vehicles (FMTV) is a series of vehicles manufactured by BAE Systems Land and Armaments based on a common chassis, which vary by payload and mission requirements. The FMTV were derived from the Austrian military truck Steyr 12M18. The Light Medium Tactical Vehicle (LMTV) has a 2.5-ton capacity (cargo and van models). The Medium Tactical Vehicle (MTV) has a 5-ton capacity (cargo and long-wheelbase cargo with and without material handling equipment, tractor, van, wrecker, and dump truck models). Three truck variants and two companion trailers, with the same cube and payload capacity as their prime movers, provide air drop capability. M1078s have been deployed to Iraq with armored cabs with roof gun mounts with shields, similar to those fitted on humvees and M113s. The cab-over FMTV replaces obsolete and maintenance-intensive 2.5 ton and 5 ton M35 and M939 series of trucks previously in the fleet and performs local and line haul, unit mobility, unit resupply, and other missions in combat, combat support and combat service support units. It is rapidly deployable worldwide and operates on primary and secondary roads, trails, and cross-country terrain, in all climatic conditions. Commonality of parts across truck chassis variants significantly reduces the logistics burden and operating and support costs. New vehicle applications are being developed to meet new requirements. The FMTV A1 series includes a 1999 Environmental Protection Agency-certified engine, upgraded transmission, electronic data bus, an anti-lock brake system and interactive electronic technical manuals. The FMTV shares its drivetrain with the Caiman MRAP vehicle. [READ THE REST OF THIS ARTICLE]





The General Electric GEnx (General Electric Next-generation) is an advanced dual rotor, axial flow, high-bypass turbofan jet engine in production by GE Aviation for the Boeing 787 and 747-8. The GEnx is intended to replace the CF6 in GE's product line. The GEnx and the Rolls-Royce Trent 1000 were selected by Boeing following a run-off between the three big engine manufacturers. The GEnx uses some technology from the GE90 turbofan, including composite fan blades, and the smaller core featured in earlier variants of the engine. The engine carries composite technology into the fan case. Both engine types will have a standard interface with the aircraft, allowing any 787 to be fitted with either GE or RR engines at any time. The engine market for the 787 is estimated at US$40 billion over the next 25 years. A first is the elimination of bleed air systems using high temperature/high pressure air from the propulsion engines to power aircraft systems such as the starting, air-conditioning and anti-ice systems. The GEnx and the Trent 1000 allow a move towards the electric airplane. The GEnx is expected to produce thrust from 53,000 to 75,000 lbf (240 to 330 kN) with first tests commencing in 2006 and service entry by 2008 (now delayed by 787 deliveries). Boeing predicts reduced fuel consumption of up to 20% and significantly quieter engines than current turbofans. A 66,500 lbf (296 kN) thrust version (GEnx-2B67) will be used on the 747-8. Unlike the initial version, for the 787, this version has a traditional bleed air system to power internal pneumatic and ventilation systems. It will also have a smaller overall diameter than the initial model to accommodate installation on the 747. General Electric began initial test runs of the bleedless GEnx variant on 19 March 2006. The first flight with one of these engines took place on 22 February 2007, using a Boeing 747-100, fitted with one GEnx engine in the number 2 (inboard LH) position. This engine is a dual rotor, axial flow, high bypass ratio turbofan. The 10-stage high pressure compressor is driven clockwise (Aft Looking Forward) by a 2-stage high pressure turbine. The single stage fan and 4-stage low pressure compressor are driven counterclockwise (Aft Looking Forward) by a 7-stage low pressure turbine. [READ THE REST OF THIS ARTICLE]



ULTra (Urban Light Transit) is a personal rapid transit system developed by ULTra PRT, (formerly known as Advanced Transport Systems). The first public system using ULTra has been constructed at London's Heathrow Airport, and has now opened to the public. To reduce fabrication costs, the ULTra uses largely off-the-shelf technologies, such as rubber tyres running on an open guideway. This approach has resulted in a system that ULTra believes to be more economical; the company reports that the total cost of the system (vehicles, infrastructure and control systems) is between 3 million and 5 million per kilometre of guideway. In the case of ULTra, the guideway can consist of as little as two parallel rows of concrete barriers, similar to the bumpers found in a parking lot. The vehicle uses these for fine guidance only; it is able to steer itself around curves by following the barriers passively. No "switching" is required on the track either, as the vehicles can make their own turns between routes based on an internal map. Since the vehicles are battery powered, there's no need for electrification along the track. Instead the vehicles recharge when parked at the stations. As a result, the trackway is similar in complexity to a conventional road surface - a light-duty one as the vehicles will not vary in weight to the extent of a tractor-trailer. Even the stations are greatly simplified; in the case of ground-level tracks, the lack of any substantial infrastructure means the vehicles can stop at any kerb. Stations at Heathrow resemble a parking lot with diagonal slots, with a rain shield similar to the awnings at a gas station. The electric-powered vehicles have four seats, can carry 500-kilogram payload, and are designed to travel at 40 kilometres per hour (25 mph) at gradients of up to 20-percent, although the company has suggested limiting operating routes to 10-percent gradients to improve passenger comfort. The vehicles can accommodate wheelchairs, shopping trolleys and other luggage in addition to the passengers. Construction of the guideway was completed in October 2008. The line is largely elevated, but includes a ground level section where the route passes under the approach to the airport's northern runway. Following various trials, including some using airport staff as test passengers, the line opened to public usage in May 2011. At that time it was described as a passenger trials. As of September 2011 it is fully operational and bus service between the business parking lot and Terminal 5 has been discontinued. The developers expect that users will wait an average of around twelve seconds with 95-percent of passengers waiting for less than one minute for their private pod which will travel up to 40 kilometres per hour (25 mph). If the pilot project is successful, BAA have indicated that they will extend the service throughout the airport and to nearby hotels using 400 pods. [READ THE REST OF THIS ARTICLE]



The Day After is an American television movie which aired on November 20, 1983, on the ABC Television Network. The film portrays a fictional nuclear war between NATO forces and the Warsaw Pact that rapidly escalates into a full scale exchange between the United States and the Soviet Union, focusing on the residents of Lawrence, Kansas and Kansas City, Missouri, as well as several family farms situated next to nearby nuclear missile silos. The film was written by Edward Hume and directed by Nicholas Meyer. The film was released on DVD on May 18, 2004. The Day After also relied heavily on footage borrowed from both other movies and declassified government films. During the attack, extensive use of stock footage was interspersed with special effects of the mushroom clouds. While the majority of the missile launches came from United States Department of Defense footage of ICBM missile tests (mainly Minuteman IIIs from Vandenberg Air Force Base adjacent to Lompoc, California), all of the stock footage of missile launches were acquired from declassified DoD film libraries and showed some missiles (specifically "Titan" missiles), that by 1982 had been decommissioned and out of service for up to fifteen years. The scenes of Air Force personnel aboard the Airborne Command Post, in the command center receiving news of the incoming attack and in the silo launching their missiles, are footage of actual military personnel during a drill and had been aired several years earlier in a 1979 CBS documentary series, "First Strike". In the original footage, the silo is "destroyed" by an incoming "attack" just moments before launching its missiles, which is why the final seconds of the launch countdown are not seen in this movie. On the night of its television broadcast (Sunday, November 20, 1983), ABC and many of its local TV stations opened several 1-800 hotlines with counselors standing by to calm jittery viewers. During the original broadcast, there were no commercial breaks after the nuclear attack. ABC also aired a live and very heated debate, hosted by Nightline's Ted Koppel, featuring scientist Carl Sagan and conservative writer William F. Buckley, Jr.. Sagan argued against nuclear proliferation, while Buckley promoted the concept of nuclear deterrence. During the debate, Sagan discussed the concept of nuclear winter and made his famous analogy, equating the arms race to "two sworn enemies standing waist-deep in gasoline, one with three matches, the other with five."
