Estes "Blue Ninja" Rocket

This is a really decent rocket kit by our favorite manufacturer, Estes, and is definitely one of the more interesting and original gifts that I've received for Christmas (from my girlfriend, thanks babe).

The video shows three flights, the first on a "C", then an "E", then another "E" for it's fatal last flight.

For all flights, the initial launch angle is set to about 15 degrees into the wind. During the last flight, the rocket tips another 10 or 15 degrees on top of that - right off the launch pad, making the initial launch angle much steeper than I had intended. Another contributing factor to the demise of the rocket was the lack of wind that was present during the previous two launches. This combination of steep angle and no wind caused the parachute to deploy while the rocket was moving at an extremely high velocity. Simulation predicts that the parachute opens at better than 150mph and 900 feet. The forces of the parachute "stopping" the rocket were too great for the shock cord, which instantly snapped. The nosecone & parachute were recovered, while the rocket traveled a parabolic (ballistic) path straight into the ground. We couldn't find the rocket due to high brush in the area.
