Welcome back to the our channel for a discussion about the dangers of landing and taking off from Aircraft Carriers. You haven’t lived life fully unless you’ve been on the flight deck during high tempo ops. I’m a USN/USMC flight test engineer and have done that. Been under a F/A-18 while it was on the cat in full burner getting ready to get shot off. We had equipment under the aircraft that had to have a final check just before a cat shot to ensure it was calibrated at the last possible moment. Under the aircraft when it’s ready to go the sound is a physical thing. You can feel it in your guts and bones. A cat shot is the ultimate rush! No roller coaster or anything can replicate that feeling. My job is to make sure the war fighter has the best tools in the world. So the aircraft's massive kinetic energy as it lands and is hooked is transfered to those cables that arrest the aircraft. Can't the energy produced by those cables (as they roll) be harnessed somehow by some kind of turbine connected to said cables? For example, it could be used to power electrical systems, generators, lights, etc. on the ship, or be stored in some massive capacitors to be used when needed?
