Fail #3

The failures this summer are beginning to get comical. Sort of like a running gag. I have no explanation for this failure, but it is obviously some sort of altimeter error, or user error pertaining to the altimeter.

As you can see in the video, the drogue charge did not fire at apogee, and then the backup motor-based ejection charge did not have enough power to separate the rocket. Finally the main charge went at 500 feet and saved the rocket. There was no damage, but I still failed to get my certification because not everything went according to plan.

One note about how the rocket fell back to earth. It's interesting how, despite my nearly 4 caliber stability, the rocket flat-spun and at times appeared to be falling backwards. What's with that? I admittedly don't understand how that happens.

Video!

Glad to see that main chute! Amazing how it drove one fin into the ground. It ended perfectly parallel to the ground, one inch above the grass. Like it was posing... Tada!
