Analysis
The pilot stated that, during landing, he was concentrating on touching down at a particular location, and he forced the airplane onto the runway at an airspeed that was too fast. The airplane bounced two or three times and traveled off the right side of the runway/taxiway into the grass where it contacted a taxiway light. The pilot stated that the brakes were ineffective due to the speed and the grass. The airplane continued across a service road where it contacted six heavy military vehicles that were among a row of parked vehicles. Both wings and the firewall were substantially damaged. The pilot stated that there was nothing mechanically wrong with the airplane.
