    World's Smallest Snake

    By Posted on 8.4.2008 7 Comments

    An evolutionary biologist at Penn State University has discovered a species of snake so small that it can fit comfortably on a quarter. The average adult of the species, a type of threadsnake named Leptotyphlops carlae, is less than four inches long. The discovery will be published in the August 4 issue of the journal Zootaxa.

    Poisonous? I think that's an obvious question...

    Planes, Trains and Supersonic Spaceships

    Commercial Flight: 2020

    The long, skinny tube has to go. Tasked with improving the nation's air transportation, NASA wants airplanes to burn 40 percent less fuel than a 777 by 2020 and 70 percent less by 2030. Not only that, it wants those same planes to be whisper-quiet. The best -- and perhaps the only -- way to reach these ambitious benchmarks is to design commercial planes more like stealth bombers and less like pencils.

    "The blended wing's widened fuselage will make for amphitheater-like seating, with long, wide rows. Of course, there will be fewer window seats..." and fewer easy accessible exits, also! Imagine this amphiteater being evacuated after a ditching, a belly landing or an aborted takeoff. For this reason, Boeing reported two years ago: "While a commercial passenger application for the BWB concept is not in Boeing's current 20-year market outlook, the Advanced Systems organization of Boeing Integrated Defense Systems' (IDS) is closely monitoring the research based on the BWB's potential as a flexible, long-range, high-capacity military aircraft". Did they changed their minds? Waiting for an official announcement from Boeing...

    Supersonic is Back (Quietly)

    By Posted on 1.17.2008 1 Comments

    When a Concorde jet on its way from Paris to New York crashed on July 25, 2000, killing all 109 people aboard and four on the ground, the event was not simply a tragedy -- it seemed a metaphor for the sorry state of supersonic air travel.

    "Environmental complaints have dogged the Concorde, which spews vast amounts of nitrogen oxides at high altitudes, causing damage to the ozone layer -- the natural atmospheric filter that protects life on Earth from the sun's ultraviolet rays. Those harmful effects were one reason that the U.S. scrapped its original supersonic jet program in 1971" What a joke! U.S. SST was scrapped because Brits and French managed to put Concorde several steps ahead of American (Boeing) design. What we see afterward was a tremendous political lobby whose main goal was only to punish the audacious Europeans for dare challenging the American aviation industry. If even today USA defy any universal regulation about emissions control, what can we say about 1971 behaviour?

    The Amazing Rusting Aluminum

    By Theodore Gray Posted on 3.17.2009 5 Comments

    Unless you are a representative of a national meteorological bureau licensed to carry a barometer (and odds are you’re not), bringing mercury onboard an airplane is strictly forbidden. Why? If it got loose, it could rust the plane to pieces before it had a chance to land. You see, airplanes are made of aluminum, and aluminum is highly unstable.

    "So no, breaking a thermometer on a plane won't destroy it." Not exactly. Mercury is really considered as "dangerous goods" and prohibited in many carriers. Those who permits requires a certified container to hold such stuff during transportation. Loading staff must be properly trained to deal with such cargo, also. Now, imagine that thermometer breaking and leaking its juice inside a plane. Heavy as it is, mercury will fall into the holes and slots of the plane structure and will, finally, reach its destination on the lowest and most inaccessible parts of the hull, performing its chemical talents in a totally disguised way. When found, will be too late: part replacement, IF possible.
