This is a 1/16 speed view of 240fps video of my rocket Disappearing Act performing its namesake with an Aerotech I1299 Warp-Nine. The rocket was predicted to accelerate at a peak of 220 g. Note that it takes only 0.05 s to clear the 4-foot launch tower. Also note the triangular aluminum rail stop which was once screwed tightly onto one of the guide rails: it got completely blown off by the thrust of the motor and was found fifteen feet away.
