It is now confirmed that a helium leak caused the scrub of the Falcon 9 May 10 launch.

According to reports, no damage occurred, but tracing the leak has apparently taken longer than expected, which explains the slip in the announced schedule.

    FAA Experimental permit for DragonFly vehicle at McGregor,TX site:,-12,214

    I preferred the notional DragonRider vs DragonFly due to the Pern reference, (And an endless series of available names, Ramoth, Mnemneth, Ruth, etc)


    – up to four steel landing legs
    – weighs 14000 lbs unfueled
    – maximum proplellant load is 400 gallons

    Four kinds of test flights expected:
    – propulsive assist landing (dropped from helicopter with chutes)
    – fully propulsive landing (dropped from helicopter)
    – propulsive assist hop (self launched, parachute deploys)
    – fully propulsive hop (like Grasshopper)

    This is gonna be totally AWESOME! The cows at McGregor are in for a series of scary days. (Or else they will be the most jaded cattle on the planet).

    Faster please! (As Glenn Reynolds likes to say).

    I can’t wait until they have launches backed up. Launches every week or two.

    Then if something like this happens they can just role the rocket off the launch pad and role the next one on for a minimal delay between launches. They are only making money of things fly.
