    It showed technological superiority over the USSR
    There was a Russian space shuttle. From http://liftoff.msfc.nasa.gov/rsa/buran.html:
    History
    The Russian Shuttle Buran ("Snowstorm" in Russian) was authorized in 1976 in response to the United States' Space Shuttle program. Building of the shuttles began in 1980, with the first full-scale Aero-Buran rolling out in 1984. Test Flights
    The first suborbital test flight of a scale model of Buran took place in July 1983. There were five additional flights of the scale model in following years. Aerodynamic tests of the full-scale Buran analogue began in 1984. This aero-Buran was worn out after 24 test flights and would not fly again. The last of these aerodynamic test flights was in April 1988. Orbital Launch
    The first and only orbital launch of the shuttle Buran was at 3:00 GMT on November 15, 1988. The flight was unmanned, as the life support system had not been checked out and the CRT displays had no software installed. The vehicle was launched on the powerful Energiya booster into an 247 by 256 km orbit at 51.6 degrees inclination. The Buran orbited the Earth twice before firing its thrusters for reentry. The flight ended at 6:25 GMT when the vehicle touched down at Tyuratum. The Buran 1 mission was limited to 2 orbits due to computer memory limitations. Aftermath
    Although the first orbital flight of Buran was unmanned, it demonstrated much promise. The autopilot that landed the shuttle was able to overcome a 34 mph crosswind to land within 5 feet of the runway center line. Also, of the 38,000 heat shield tiles that covered Buran, only 5 were missing. Cancellation
    After the first flight of Buran, funding for the project was cut. Although the project wasn't officially canceled until 1993, much of the work was halted long before that date. There were two other Buran shuttles under construction. The second orbiter, "Ptichka" ("Little Bird" in Russian) was originally scheduled for completion in 1990. The third Buran was due in 1992. Neither was finished. In November 1995, the partially completed shuttles were dismantled at their production site. The manufacturing plant is scheduled to be converted for production of buses, syringes, and diapers.

    I don't believe the toxic rocket fuel line. Here's why:
    1. The tanks were nearly empty. This was at an _END_ of a mission. Granted there may have been reserves on board, but what needed to be used was used. The main engines were dry, and what was left was purely maneuvering fuel.
    2. The percentage of the total mass of the shuttle that the fuel occupied is very small. Most of what feel were structural components.
    3. Considering the number of pieces the Columbia broke into, it doesn't seem likely that any of the tanks survived intact, aka sealed.
    4. Heat. IIRC, the shuttle broke up at Mach 18. It turned into a fireball that streaked through the sky. It is logical to assume that much of the fuel had burned away (or chemically changed) once it contacted the plasma around the vehicle.
    5. Wind. Skydivers jumping from 10,000 feet (2 miles) experience wind above 100 mph. The shuttle hit the atmosphere at supersonic speeds. Any remaining liquid would likely evaporate during the fall. Even if the liquid boils at 500C, the speeds at which the components were traveling would create dynamic pressures so low that any liquid in contact with the boundary layers would evapaorate. In short, liquids traveling at that speed would cavitate. Simpler reason: the liquid would blow off.
    6. IIRC, the shuttle broke up 20 miles above the earth. According to standard atmospheric tables, the air pressure would be 0.32" Hg, 1% of that at sea level. Lower air pressure makes it easier for liquids to evaporate.

    If they didn't retrofit Enterprise after Challenger, what makes you think they'd do that now?

    More info on Enterprise(OV-101) from http://science.ksc.nasa.gov/shuttle/resources/orbi ters/enterprise.html

    Enterprise, the first Space Shuttle Orbiter, was originally to be named Constitution (in honor of the U.S. Constitution's Bicentennial). However, viewers of the popular TV Science Fiction show Star Trek started a write-in campaign urging the White House to select the name Enterprise. Designated, OV-101, the vehicle was rolled out of Rockwell's Air Force Plant 42, Site 1 Palmdale California assembly facility on Sept. 17, 1976. On Jan. 31, 1977, it was transported 36 miles overland from Rockwell's assembly facility to NASA's Dryden Flight Research Facility at Edwards Air Force Base for the approach and landing test program.

    The nine-month-long ALT program was conducted from February through November 1977 at the Dryden Flight Research Facility and demonstrated that the orbiter could fly in the atmosphere and land like an airplane, except without power-gliding flight.

    Click here for the JSC Shuttle Approach and Landing Test Image server.

    Two NASA astronaut crews-Fred Haise and Gordon Fullerton and Joe Engle and Dick Truly-took turns flying the 150,000-pound spacecraft to free-flight landings.

    The ALT program involved ground tests and flight tests. The ground tests included taxi tests of the 747 shuttle carrier aircraft with the Enterprise mated atop the SCA to determine structural loads and responses and assess the mated capability in ground handling and control characteristics up to flight takeoff speed. The taxi tests also validated 747 steering and braking with the orbiter attached. A ground test of orbiter systems followed the unmanned captive tests. All orbiter systems were activated as they would be in atmospheric flight. This was the final preparation for the manned captive flight phase.

    Five captive flights of the Enterprise mounted atop the SCA with the Enterprise unmanned and Enterprise's systems inert were conducted to assess the structural integrity and performance handling qualities of the mated craft.

    Three manned captive flights that followed the five captive flights included an astronaut crew aboard the orbiter operating its flight control systems while the orbiter remained perched atop the SCA. These flights were designed to exercise and evaluate all systems in the flight environment in preparation for the orbiter release (free) flights. They included flutter tests of the mated craft at low and high speed, a separation trajectory test and a dress rehearsal for the first orbiter free flight.

    In the five free flights the astronaut crew separated the spacecraft from the SCA and maneuvered to a landing at Edwards Air Force Base. In the first four such flights the landing was on a dry lake bed; in the fifth, the landing was on Edwards' main concrete runway under conditions simulating a return from space. The last two free flights were made without the tail cone, which is the spacecraft's configuration during an actual landing from Earth orbit. These flights verified the orbiter's pilot-guided approach and landing capability; demonstrated the orbiter's subsonic terminal area energy management autoland approach capability; and verified the orbiter's subsonic airworthiness, integrated system operation and selected subsystems in preparation for the first manned orbital flight. The flights demonstrated the orbiter's ability to approach and land safely with a minimum gross weight and using several center-of-gravity configurations.

    For all of the captive flights and the first three free flights, the orbiter was outfitted with a tail cone covering its aft section to reduce aerodynamic drag and turbulence. The final two free flights were without the tail cone, and the three simulated space shuttle main engines and two orbital maneuvering system engines were exposed aerodynamically.

    The final phase of the ALT program prepared the spacecraft for four ferry flights. Fluid systems were drained and purged, the tail cone was reinstalled, and elevon locks were installed. The forward attachment strut was replaced to lower the orbiter's cant from 6 to 3 degrees. This reduces drag to the mated vehicles during the ferry flights.

    After the ferry flight tests, OV-101 was returned to the NASA hangar at the Dryden Flight Research Facility and modified for vertical ground vibration tests at the Marshall Space Flight Center, Huntsville, Ala.

    On March 13, 1978, the Enterprise was ferried atop the SCA to NASA's Marshall Space Flight Center, where it was mated with the external tank and solid rocket boosters and subjected to a series of vertical ground vibration tests. These tested the mated configuration's critical structural dynamic response modes, which were assessed against analytical math models used to design the various element interfaces.

    These were completed in March 1979. On April 10, 1979, the Enterprise was ferried to the Kennedy Space Center. mated with the external tank and solid rocket boosters and transported via the mobile launcher platform to Launch Complex 39-A. At Launch Complex 39-A, the Enterprise served as a practice and launch complex fit-check verification tool representing the flight vehicles.

    It was ferried back to NASA's Dryden Flight Research Facility on Aug. 16, 1979, and then returned overland to Rockwell's Palmdale final assembly facility on Oct. 30, 1979. Certain components were refurbished for use on flight vehicles being assembled at Palmdale. The Enterprise was then returned overland to the Dryden Flight Research Facility on Sept. 6, 1981.

    During May and June of 1983, Enterprise was ferried to the Paris, France, Air Show, as well as to Germany, Italy, England and Canada, and was returned to the Dryden Flight Research Facility.

    In the April-October 1984 time period, Enterprise was ferried to Vandenberg Air Force Base in California and to Mobile, Ala. From there it was taken by barge to New Orleans, La., for the United States 1984 World's Fair.

    In November 1984 it was ferried to Vandenberg Air Force Base and used as a practice and fit-check verification tool. On May 24, 1985, Enterprise was ferried from Vandenberg Air Force Base to NASA's Dryden Flight Research Facility.

    On Sept. 20, 1985, Enterprise was ferried from Dryden Flight Research Facility to the Kennedy Space Center in Florida. On Nov. 18, 1985, Enterprise was ferried from the Kennedy Space Center to Dulles Airport, Washington, D.C., and became the property of the Smithsonian Institution. The Enterprise was built as a test vehicle and is not equipped for space flight.

    Following in the Enterprise's, the orbiter Columbia was created and it became the first Space Shuttle to fly into Earth orbit in 1981. Four sister ships joined the fleet over the next 10 years: Challenger, arriving in 1982 but destroyed four years later; Discovery, 1983; Atlantis, 1985; and Endeavour, built as a replacement for Challenger, 1991.

    In the day-to-day world of Shuttle operations and processing, Space Shuttle orbiters go by a more prosaic designation. Enterprise is commonly refered to as OV-101, for Orbiter Vehicle-101.

    After the settlement of the strike and the successful launch of their ADR stock, Sony had returned to normal. An eventful 1961 drew to a close on December 16, when Sony concluded a contract with Paramount Pictures to provide technical assistance in the production of a chromatron tube and color television receiver utilizing it.

    The days of radio are over. The future lies in television. Ibuka's simple comment resulted in the birth of Sony's model TV8-301, the world's first portable television. It was, however, a black and white receiver.

    We are surrounded by vivid colors in our daily life. Television, then, must be true to life. A TV set that cannot reproduce color is far from having been perfected. Producing color TVs was the next logical step for anyone involved in television. Sony was no exception. Many people had taken part in the technical research of color TVs from the earliest days of television. Early color receivers used cathode-ray tubes developed by RCA, which employed the three-electron gun shadow mask system. These cathode-ray tubes had three major drawbacks however: they were expensive, difficult to tune and broke down often. In comparison with black and white sets, the images were much darker. Moreover, when viewed in a normally lit room, the beautiful colors did not come through. Colors often ran into one another --- in general it was difficult to attain an accurate picture.

    The consensus was that the dark picture and failure to produce true color did not merit the high price. This feeling accounted for the slow sales of color sets. In the U.S., the ratio of B/W TV owners to color TV owners was 50 to 1 (50 million to 1 million). In Japan, the situation was worse, with only 300 color receivers sold in contrast to nine million B/W sets.

    Ibuka and the others decided that if they were going to tackle color TV, they would not rely on the shadow mask process with all its drawbacks. The Sony staff was confident that they could come up with a television without precedent. Sony is an innovator. We do things that no one has done. With this, Sony began the urgent search for a replacement to the shadow mask.

    The SV-201 all-transistor VTR.

    Sony was not alone. Dissatisfaction with the shadow mask screen was widespread. One possible substitute was the banana tube. Television signals were sent through this long thin tube, followed by RGB signals flashed at timed intervals, shuttered through a striped filter rotated through the beam. The rotating sound made a clattering noise, which in Japanese is onomatopoetically referred to as karakara. The color television using it was given the dubious, but amusing, name of karakara television, because of its phonetic closeness to the word color. The apple tube, which had been developed by Philco, was another possibility. Then there was the chromatron tube. This was the invention of famous American atomic physicist and Nobel laureate, Dr. E. O. Lawrence.

    In March 1961, Kihara and his staff took part in the IRE Show which was held at the New York Hilton Hotel and the New York Coliseum. An exhibit of the latest technology and technological applications, this was more like a scientific exposition than the present day trade show. Kihara and his staff had brought along the SV-201, the world's smallest video recorder and Hi-D (high-density) metal powder-coated tape which had been developed for the recorder.

    Here at the show, the Sony staff came across the brightest color display they had ever seen. It had originally been conceived as an IFF (Identification of Friend or Foe) display for military use. At one glance, however, Kihara knew that it was what they had been looking for.
