We've updated the main website with the FTC flights report from last Sunday. Included is a short video of the highlights from the day.
In putting together the pictures and video for the update we noticed that in both of the last two higher pressure flights the rocket was bending quite a bit on take off. This probably explains the lower than expected altitude. The rocket is very flexible and under the acceleration loading it just bends. This is likely to be inducing fairly large drag.
