As Andrew indicated, we did indeed get the beast off the pad.
Unfortunately, the flight wasn't optimal, but it wasn't a complete disaster either...
On liftoff, the rocket started to come up reasonably straight, then arced to the northwest (wind was out of the southwest). The boosters popped off beautifully and every one recovered under a parachute. The explosive bolts did their thing and we got both mains plus the nosecone parachute out.
Unfortunately, the booster section stripped its chute, so it came in ballistic and is a total loss. The boosters have a few dings but are in good shape. The upper main has some serious road rash from getting dragged over the ground by the main.
Post-mortem shows that the central P motor was tardy coming up to pressure and didn't provide us any thrust until we were at, or just past, the end of the rails, which allows the rocket to tip over a bit.
As the P tailed off on thrust, the rocket started to dip down, so the altimeters did their thing and popped the mains. The pilot chute for the lower main pulled the recovery harness back into the still-burning motor, compromising its integrity, which is why we stripped the chute. The parachute itself is in perfect condition, and other than some Kansas dust, looks like it has never been used.
We'll have more flight photos and video available in time...
