A rare catch of a fleeting midair moment – the forward retention for the solid-fuel motor has failed and so it thusts forward up through the rocket, pushing the parachute and nose cone out prematurely.

For some reason, the Aerotech Sumo seems prone to all sorts of airborne high jinks.

Just got back from the LUNAR Snow Ranch launch, and it was full of excitement and mishap…. more later….

  1. I would not want to be in THAT rocket! Great catch.

    Speaking of mishaps, some kind of explosion was heard and look what happened to one of our national historic sits of Canada in Québec City. View photos to the end. I hope more will be sent (I know of more) so I can add them here.
    Manège Militaire à Québec. We were told that it will be rebuilt as it is too important.

  2. Yikes! Where is the motor at this point? Is it nearly used up i.e. that little bit of flaming stuff at the tail-end of the front section? That doesn’t look like a motor to me (a complete ignoramus on these matters) as it seems to be too thin and the gases it is giving off appear to be a lot less than what was going on split-seconds earlier (the smoke of which is still visible behind the tail section). Or is it perhaps an exothermic core section of the motor which has shot out, separating from and leaving an outer shroud of endothermic propellant in the after part of the body – which still appears to be exuding some flame?

  3. Lucky shot!!! Great 🙂

  4. @jitze: Hmmm….. very interterting – I’ll have to locate the owner to ask about the post-mortem… The sparky stick looks like the full length of motor from the images. Looking at the frame 1/3 sec earlier, it looks like some or all of the nozzle popped out the back, creating a big flame out, but depressurizing the motor. So here we see it sputtering out.

    update: looking at the frames afterward, the forward bulkhead is still attached to the motor! So the motor, phenolic motor tube and forward wooden disc all look like they popped forward. Makes me wonder if weak glues were used….

  5. Yes, nice title. I hate things that are premature! …. generally.

  6. Great catch! Man that Sumo kit is Jinxed! I see a number of postings about rebuilt Sumos. Good news that they can have a successful 2nd life.
