USAF Colonel John Stapp tests rocket sled to determine ejection safety for pilots traveling at supersonic speeds

The video describes a groundbreaking experiment at Holloman Air Force Base, where Lieutenant Colonel John P. Stapp rides a rocket sled to test safety measures for pilots ejecting at supersonic speeds. The sled, equipped with 4,500-pound thrust rockets and no wheels, uses slippers to glide down a track. A water brake system controls deceleration, and a slow-motion camera captures the effects on Stapp. Reaching 421 mph, Stapp emerges unscathed, highlighting the experiment's success in enhancing pilot safety.

What is the primary reason for not using wheels on the rocket sled?

• Wheels are too expensive.

• Wheels would fly apart at high speeds.

• Wheels are too heavy.

• Wheels are not aerodynamic.

Where is the rocket sled experiment conducted?

• Holloman Air Force Base

• Area 51

• Edwards Air Force Base

• Cape Canaveral

What is the main goal of the rocket sled experiment?

• To ensure pilot safety during supersonic ejections

• To develop faster aircraft

• To test new rocket designs

• To break the sound barrier

How is deceleration controlled in the rocket sled experiment?

• By reversing the rockets

• With a pool of water between the tracks

• Using parachutes

• With air brakes

What speed did Colonel Stapp reach during the experiment?

• 300 miles per hour

• 421 miles per hour

• 600 miles per hour

• 500 miles per hour
