Space Shuttle Challenger barrage & access filmed from the Shuttle Landing Facility (SLF)

Author: admin

STS 51-L Launch 01/28/1986 filmed from TV Van #2 at the Shuttle Landing Facility (SLF) on site at Kennedy Space Center. This video was made from a copy of a ¾ videotape received from NASA under provisions of the Freedom of Information Act. This video is not copyrighted. Its wide distribution is welcome as an aid in understanding the experience of watching the disaster unfold in person. STS-51-L crew: Dick Scobee, Michael J. Smith, Ronald McNair, Ellison Onizuka, Christa McAuliffe, Gregory Jarvis & Judith Resnik. The shuttle was designed to withstand a load factor of 3 (or 3 g), with another 1.5 g safety factor built in. The crew cabin in particular is a very robust section of the shuttle because of its design and construction of reinforced aluminum. During vehicle breakup, the crew cabin detached in one piece and slowly tumbled into a ballistic arc. NASA estimated the load factor at separation to be between 12 and 20 g; however, within two seconds it had already dropped to below 4 g and within ten seconds the cabin was in free fall. The forces involved at this stage were likely insufficient to cause major injury. At least some of the astronauts were likely alive and briefly conscious after the breakup, as three of the four Personal Egress Air Packs (PEAPs) on the flight deck were found to have been activated. Investigators found their remaining unused air supply roughly consistent with the expected consumption during the 2 minute 45 second post-breakup trajectory. While …

Coast To Coast AM – 6.11.2011 – 1/4 – Impending Energy War

Author: admin

MP3 www.4shared.com Guests: Freddy Silva, David Hagberg Impending Energy War: On Sunday night’s program, George Noory was joined by writer David Hagberg, who shared his belief that an impending global energy war is currently brewing. He explained that oil-rich countries dependant on the export income, as well as holders of oil fund derivatives, are at the heart of this energy war. The ultimate goal, Hagberg said, is to perpetuate oil dependence and dissuade the development of alternative energy solutions. Based on his research, Hagberg foresees eventual terrorist attacks on nuclear power plants which will make such energy production unpalatable for Americans. Additionally, sabotage of the power grid system in the United States would result in skyrocketing electrical prices, making oil-based energy even more appealing. In detailing one of the “early shots” in this energy war, Hagberg cited a 2009 article from the Wall Street Journal. In the story, it was revealed that the computer systems which control the flow of electricity in America have been compromised by a tenacious computer virus. “With the push of a button, they could shut down all the electricity in the United States,” he warned. The virus is so sophisticated, he said, that experts believe it could only have come from China or Russia and attempting to remove it would collapse the electrical system in America. Hagberg noted that geopolitical analysts believe these countries would not use the virus to knock out our …

The First Nuclear Related Fatality & Accident In America – Emergency Response – Documentary Video

Author: admin

US Atomic Energy Commission Idaho Operations Office SL-1 The Accident: Phases I and II A13886VNB1 Describes this nuclear accident from the point of view of the Atomic Energy Commission. Considering the time, this film report is exceptionally candid about the vulnerabilities of nuclear reactors. This first civilian reactor accident was especially gruesome in that one of the reactor operators was shot into the ceiling by an expelled reactor vessel plug and control rod. Views of the internal wreckage are fascinating. The cause of this accident has never been determined, although operator error has been alleged. Documentaries of this quality are rare in the US nuclear community, at least for the general public. Producer: US Atomic Energy Commission; Creative Commons license: Public Domain The SL-1, or Stationary Low-Power Reactor Number One, was a United States Army experimental nuclear power reactor which underwent a steam explosion and meltdown in January 1961, killing its three operators. The direct cause was the improper withdrawal of the only movable control rod. The event is the only fatal reactor accident in the United States. The facility, located at the National Reactor Testing Station approximately forty miles (60 km) west of Idaho Falls, Idaho, was part of the Army Nuclear Power Program and was known as the Argonne Low Power Reactor (ALPR) during its design and build phase. It was intended to provide electrical power and heat for small, remote military facilities …

Electric Fireplaces – Realistic Looking Fireplace Options

Author: admin

If you are looking to add some warmth and comfort to your home then you have several options worth considering. One of the best things you can do to add warmth to your home is to install electric fireplaces. Electric fireplaces will create a very inviting space and they are extremely easy to install as compared to other fireplace options.

When hunting to add a recess to your residence you have several options. If you are practice building your bag then you have the flexibility to add either a director burning recess or a gas hearth. It is real unrealistic tho’ to add a director burning fireplace to an existing bag that is not outfitted with a chimney. A latent option in this individual is a gas fiery recess but this can be valuable if a gas bloodline needs to be run.

Here are the reasons why so many people like electric fireplaces. You don’t need to have access to a full sized chimney or a gas line. This means that you can have a fireplace anywhere in your house, since you will probably have electricity available in every wall. If you have existing construction, an electric fireplace will be a lot more affordable.

Folks love wood burning hearths because they look so rustic, warm, and welcoming. You can now achieve the same sort of attractive appearance with a contemporary electric fireplace. There are many models of realistic-looking ones. You can also choose from a broad assortment of electric fireplace mantelpieces that will coordinate beautifully with any type or period of decor.

You may also obtain quite realistic looking wood fireplace surrounds which will help make the fireplace appear to be a natural, wood-burning unit. Modern surrounds feature very intricate detail, while the artificial logs will appear as if they’re truly burning. These logs also come with embers and varied glows to give them the appearance of authentic logs.

If you are looking to create an extremely inviting space then there is no better way to do it then to install a fireplace. This will create a very welcoming space that will bring most people very pleasant memories. Regardless of the current configuration of your home you can find a fireplace that will work for you.
