    That is very sad. I saw it fly past at Oshkosh 2013.

    Sad deal for sure.....

    It will be interesting to see what actually broke and caused the crash.....

    Hopefully there is a video or 2 of it....

    A bit more info, but very little more here:

    There should also be web coverage this weekend of the races.

    Witnesses reported it broke up in flight.
    I wonder if this was the fastest wood racer of all time?

    I wonder if there might have been undetected internal damage from this earlier event:

    Yeh, that is a possible factor.
    I was wondering if the low modulus of elasticity of wood is carefully considered in the design at these speeds. (+378mph)
    The low E off wood, much less than steel, aluminum and carbon would be a factor in the aeroelastic properties of the airframe, I think.

    The big question in my mind is whether there's more than one GP-5? I should know the answer to that, but I don't. Was this the one-and-only example?

    Reading the "tone" of the news story, it seems like these crashes don't do much to help the safety reputation of aviation?

    It gives cause to question the whole premise of the 'cheap air racing to promote aviation' thread.

    Yey, that's why I was arguing for a slow race... But with little success.
    Building small, cheap, fast racers with tiny unproven engines for 250 pound pilots doesn't make sense to me.
    I dropped off that thread.

    Air racers, like automobile racers, are going to crash. It happens. Exactly as it is with auto racing, it's a PR problem with the general public. The pilots judge the risk for themselves.

    That would be a race of the slowest plane wins. That's actually difficult to do with a minimum wing load.

    It doesn't help much with the public perception of the safety of aviation. But high-performance air racing has about as much relevance to general civil aviation as military aviation does.

    Like this one? --> CAFE Foundation

    It's not actually a slow race, but factors in multiple variables in addition to time (weight, passengers, fuel burn, etc.)

    Neat stuff (for me at least)

    No, they are all about electric, not cheap.
    I proposed a return to the 1924 Lympne Trials. It was best miles per gallon. The winner was 87.5 mpg.
    Speed and other criteria were also part of the race formula.
    Read about at: flightglobal.com (archives 1923-24)

    I liked the old competition to maximize the ratio of top speed to stall speed.

    Napier Heston Racer? Was the GP-5 shown to be faster?
