Two veteran Florida Highway Patrol troopers who flew an agency plane into restricted airspace for a closer look at the space shuttle Discovery Sept. 29 will be suspended up to two days, authorities said.

Maj. Withrop Vincent and Sgt. Gary Schluter, the pilot, "flew 45 miles out of their flight path expressly to view the launch" at Kennedy Space Center, Maj. Mike Kirby said Friday. "That's not acceptable."The troopers, who were headed to Orlando on official business the morning of the mission, entered restricted airspace before the launch but left before liftoff, federal authorities said. No charges were filed.

Vincent, a troop commander in West Palm Beach, will be suspended without pay for two days, Kirby said. Schluter will be suspended for one day.

The troopers were relieved of duty when the investigation began but returned to work Oct. 25, Kirby said.
