This is a big rocket that they're sending up. For example, here's some of the data from their preliminary simulations as they calculate the best timing to deploy the chutes on the dropaway boosters.
Each booster is 9" dia, 8' tall weighing about 20 lbs at burnout. Boosters are connected fore and aft and will be released by blowing charges at both connection points. Vehicle will be traveling 404 mph at 2600' at time of release (6 seconds into the flight) CG on the booster will be slightly forward of center (maybe 12")
I suspect the large surface area and low weight will cause the booster to slow rapidly, compared to the main rocket weighing about 90 lbs, carrying much more inertia.
This weekend was the scheduled maiden flight from the field down at Whitakers, North Carolina. I don't have a link to the liftoff pictures yet, but here's one of the Titan IV on the pad as they prep before flight.
