Building, flying, and attempting to recover a 98mm min. dia. rocket

Recovery of hpr rockets is always difficult, and the challenge grows exponentially as altitude increases beyond 10,000 feet. My longest recovery was also at Black Rock, but in my case the rocket was small (2.5 inches by 72 inches) and the distance was only about a mile or maybe 1.5 miles at most. We lost sight of the rocket on the way down, but did know the general location. After driving out a ways, it came back into view on the ground and was recovered no problem. Flights to extremely high altitude, 50,000 feet and beyond, frequently fail during thrust, at max Q, on recovery, or they get lost somewhere on the ground. It is very difficult to get everything working perfectly.
