A second flight was planned for February 10 2024, with the I-470 booster staging to the same I-175 used in the first flight. Predicted altitude was 7000 feet AGL. Sadly, this flight had to be cancelled due to low cloud cover at the launch site.

Gravity's Just a Habit ("GJaH") is my first two-stage high-power rocket. The initial build took place between May and July 2021, and I had it finished by November for its first flight.

GJaH is built from a Wildman Shapeshifter Jr. with the optional booster kit. I built a Shapeshifter Jr. for my level 1 certification in 2013, and my initial idea was to just build a booster for it, but then I decided I was sentimental enough about that rocket to just build a whole new one. The booster fins are reversed from the normal orientation (with the curved edge facing backwards) just because I liked the way it looked.

The rocket was not stable enough while flying on the booster, and was well outside its tilt limit when it would have staged.
