A little video about the day I got to putter around in a Ford Tri-Motor!

Liberty Aviation Museum’s 1928 Ford Tri-Motor 5-AT-B, serial No. 8, flew its first flight on December 1, 1928. It was sold to Transcontinental Air Transport (TAT, the logo that graces the aircraft’s fuselage today) in January 1929 where it became NC9645 and was named City of Wichita. It inaugurated westbound transcontinental commercial air service on July 7, 1929, with sister ship City of Columbus. In April 1931, ownership of the aircraft was transferred to Transcontinental and Western Air (TWA). Here the aircraft helped in the development of TWA’s route system. In July 1935, NC9645 was sold to G. Ruckstill and entered the fleet at Grand Canyon Airlines. From there the Tin Goose was sold to Boulder Dam Tours in February 1937, where it entered sightseeing air tour service. The Ford was registered AN-AAS with Transportes Aereos del Continente Americano (simply known as TACA Airlines) in Honduras in December 1937, where it stayed until 1942 when purchased by an unknown operator in Compeche, Mexico, and was reregistered as XA-FUB. The registration changed again in 1950 to XA-NET while under the ownership of another individual in Compeche. 1951 brought major overhaul and repairs for No. 8, including removal of the aircraft’s corrugated skin, which was replaced with flat sheet metal. This change earned the aircraft nickname “the smooth-skin Ford.” The Tri-Motor was sold to another private owner in July 1953 and was damaged in an accident in January 1954, after which it was put in storage. Eugene Frank of Caldwell, Idaho, acquired the aircraft in 1955, moving it back to the U.S. and reregistering it as N58996. It remained in storage until July 1964, when it was purchased by Nevada’s William F. Harrah of Harrah’s Hotel and Casinos. Harrah returned the plane’s registration to NC9645 and began an extensive seven-year renovation, bringing the aircraft back to airworthy status and restoring the corrugated skin. The former smooth-skin Ford had its first post-restoration flight in 1971 and flew in Reno several times before being moved to static display as part of Harrah’s impressive automobile collection. After Harrah’s death, parts of his collection, including NC9645, were auctioned off in June 1986 to high bidder Gary Norton of Athol, Idaho. In February 1990, the Evergreen Aviation and Space Museum in McMinnville, Oregon, acquired the aircraft. It remained in storage there until 1996 when another restoration of the aircraft started, returning it to flying condition once again. In 2014, the aircraft was acquired by Ed Patrick and the Liberty Aviation Museum in Port Clinton, Ohio. Volunteers ferried the aircraft across the country to its new home. After further maintenance to ensure the aircraft was tour-ready, Liberty entered into a lease agreement with EAA, working together to showcase the historic aircraft around the country.

Horribly Trashed Archaeological Site

There is a disturbing trend of trashed, defaced and vandalized ancient archaeological sites. It needs to stop. This video is another sad example of a sacred archaeological site that has been used as a trash dump. This site location is being kept secret at the request of the archaeological team studying the site.

The search for extraterrestrial intelligence (SETI) is a collective term for scientific searches for intelligent extraterrestrial life, for example, monitoring electromagnetic radiation for signs of transmissions from civilizations on other planets. 

 Scientific investigation began shortly after the advent of radio in the early 1900s, and focused international efforts have been going on since the 1980s. In 2015, Stephen Hawking and Russian billionaire Yuri Milner announced a well-funded effort called Breakthrough Listen.

If you are an avionics A&P, automotive technician, HAM radio operator or a DIY electronic hobbyist, you will need a DC power supply for your work bench. Here I review the basics as I unbox a MFJ 4035MV power supply.

A power supply is an electrical device that supplies electric power to an electrical load. The primary function of a power supply is to convert electric current from a source to the correct voltage, current, and frequency to power the load. As a result, power supplies are sometimes referred to as electric power converters. Some power supplies are separate standalone pieces of equipment, while others are built into the load appliances that they power. Examples of the latter include power supplies found in desktop computers and consumer electronics devices. Other functions that power supplies may perform include limiting the current drawn by the load to safe levels, shutting off the current in the event of an electrical fault, power conditioning to prevent electronic noise or voltage surges on the input from reaching the load, power-factor correction, and storing energy so it can continue to power the load in the event of a temporary interruption in the source power (uninterruptible power supply). 

 All power supplies have a power input connection, which receives energy in the form of electric current from a source, and one or more power output connections that deliver current to the load. The source power may come from the electric power grid, such as an electrical outlet, energy storage devices such as batteries or fuel cells, generators or alternators, solar power converters, or another power supply. The input and output are usually hardwired circuit connections, though some power supplies employ wireless energy transfer to power their loads without wired connections. Some power supplies have other types of inputs and outputs as well, for functions such as external monitoring and control.

Video Details

June 1, 1969 KCET USA/CA Richard Burton reads poems celebrating the wonders of the cosmos in "The Violent Universe .” Discoveries that are revolutionizing astronomy and changing men’s notions of the cosmos are examined in this broadcast of “The Violent Universe.” a two-and-a-half hour program presented by Public Broadcast Laboratory.

The broadcast ranges from observatories in Europe to observatories in Australia, and from an observatory orbiting in space to one sunk a mile underground at the bottom of a gold mine in the South Dakota Badlands. Some 30 distinguished astronomers are seen at work in their observatories. Among them are Sir Bernard Lovell at Jodrell Bank, England; Thomas Gold at the giant Arecibo radiotelescope, high in the hills of Puerto Rico; Bernard Mills hunting pulsars at Mount Stromlo in Australia; Jan Cort at Dwingeloo in Holland; Maarten Schmidt at Palomar; Sir Martin Ryle at Cambridge, England; Tom Kinman at Lick, California; Frank Low in his Lear Jet “observatory” flying his telescope above cloud cover; and Donald Kniffen sending up a gamma-ray tracking chamber in a balloon.

The birth and death of stars, the possibilities of hitherto unknown sources of energy out in the stars, and quasars that act in ways nothing known in physics can explain, are examined by Robert Dicke of Princeton, Jesse Greenstein of Palomar and Mount Wilson, Allan Sandage and Bernard Pagel of the Royal Greenwich Observatory, physicist Philip Morrison of M.I.T., and Richard Henry’, rocket researcher at the United States Naval Research Laboratory.

Did the universe begin in a week’s time, with one explosion, as proponents of the “Big Bang” theory argue, or is it continually expanding in a relatively orderly way through all time, as defenders of the “Steady State” theory maintain? The controversy, which has implications for theology as well as for the movement of man out into space, is described in the broadcast.

The broadcast goes to Japan to visit the home of Tsutomu Seki, the amateur astronomer who teaches classical guitar for a livelihood and who in 1965, with Kaoru Keya, discovered the Ikeya- Seki comet. Featured in the broadcast is a studio reconstruction of a section of the universe, with 100 stars hung in their proper perspective in space.

The astronomical proportions involved in the scale replica are so vast that one foot of studio floor equals three light years—or 18,000,000,000,000 (18 trillion) —miles. The script of “The Violent Universe” was written by Nigel Calder. Narrator is Carl Sagan, professor of astronomy at Cornell, with Robert MacNeil, PBL special correspondent in London who is also a reporter for the BBC.

The Orbiting Astronomical Observatory (OAO) satellites were a series of four American space observatories launched by NASA between 1966 and 1972, managed by NASA Chief of Astronomy Nancy Grace Roman. These observatories, including the first successful space telescope, provided the first high-quality observations of many objects in ultraviolet light. Although two OAO missions were failures, the success of the other two increased awareness within the astronomical community of the benefits of space-based observations, and led to the instigation of the Hubble Space Telescope.

The Lick Observatory is an astronomical observatory owned and operated by the University of California. It is on the summit of Mount Hamilton, in the Diablo Range just east of San Jose, California, United States. The observatory is managed by the University of California Observatories, with headquarters on the University of California, Santa Cruz campus, where its scientific staff moved in the mid-1960s. It is named after James Lick.

Fast Radio Bursts and the Bochenek Magnetar | SciWorx

I am fascinated by fast radio bursts. These are powerful celestial objects that can take the same amount of energy that our sun produces in three days and blast it all out in a single millisecond. Until recently, we have never seen them in our galaxy, nor have we seen one erupt more than once. Well, things certainly have changed over at the Owens Valley Radio Observatory.
