The Death-Defying Mechanics Of Fighter Jet Ejections

Ejecting from a fighter jet may seem like a straightforward procedure, but in reality, it is a complicated and dangerous process that leaves most pilots with severe injuries. The ejection seat is the most critical piece of equipment within a fighter jet, and it is what often makes the difference between life and death. When the pilot pulls the handle, it sends an electrical impulse to the aircraft, which releases the bolts holding the cockpit's canopy in place. Small rockets in the front push the canopy up and out of the pilot's way, and an explosive cartridge underneath the seat catapults the pilot out of the cockpit. 

This initiates the seat's rocket boosters, which propel the pilot upward, and sensors within the seat measure the plane's speed and the ambient air pressure to determine whether the pilot is at a low altitude and the parachute needs to be deployed immediately or whether they're at a higher altitude, and the parachute needs to be delayed until they reach thicker air. In the latter case, the seat will still deploy a smaller shot known as a drug, which helps lower the pilot's rate of descent and stabilize the seat from careening into a deadly spin.

Once the main parachute is deployed, a motor automatically fires, finally releasing the pilot from the seat. This entire process exerts 14 to 16 times the force of gravity on fighter pilots' bodies. If pilots have time to prepare, the best thing to do is to try and make themselves skinny, stiff, and straight. Because this thing's going to go off the rails as a catapult and it's going to fire the pilot up about 50 G’s (Ground Speed) per second, and then the rocket's going to go off, and depending on where they are and what's around them, it's 5 to 20 G's(Ground Speed)  going up those rails, and within two to four seconds, depending on what mode of flight they're in, they're going to have a full parachute.

Once the pilot is in a full chute, the game's not over yet. There are still things that come into the survival piece. It's a deadly process, and even if it's slow, it's still extremely fatal. Lieutenant Colonel Pete Smith, an Air Force veteran who spent his 28th year military career as a fighter pilot and has experienced an injection firsthand, shared his experience of ejecting from his jet. He waited till about 2,000 feet which is where he pulled the pull handle and had less than a second left to live. 

In 2007, Smith had a harrowing experience while practicing a high-risk flight maneuver during training off the coast of Florida. Essentially, he was low and high speed with spatially disoriented, fighting over the water at night, and he had rolled his plane inverted and didn't even notice from the visual cues outside that that's what happened. Passing 6,000 feet, he made the decision to continue, but he should have gotten out of there out of control at 6,000 feet. But he decided to hang with it, and he's trying to slow down because he was already going 600 knots, which is equivalent to 690 miles per hour.

Smith waited till about 2,000 feet to eject, and he had less than a second left to live. He went out around 500 miles an hour, and he said that any ejection, no matter how slow or fast, was extremely violent. To this day, he remembers his body position when he went out because it snapped him back to the right. It was taking the air out of his lungs. It was like falling out of a tree and getting the wind knocked out of you. The whole thing was less than nine seconds from recognition to being in the water, and Smith had injuries, but he didn't let them stop him from flying again. He underwent physical therapy and eventually returned to flying status.

Ejecting from a fighter jet is not only physically traumatic but also emotionally challenging. Pilots invest years of training and dedication to become a fighter pilot, and when they eject, they are forced to abandon their aircraft and their mission. It takes immense courage and discipline to make the split-second decision to eject from a plane, and even then, there is no guarantee of survival. In the event of an ejection, pilots must remain calm and focused, relying on their training and equipment to survive.

Ejecting from a fighter jet is a complex and perilous procedure that can have devastating physical and emotional consequences. Fighter pilots invest significant amounts of time and effort into their training and their aircraft, making it difficult to abandon them in an emergency. Despite this, pilots must remain composed and rely on their training and equipment to survive. The ejection seat is a crucial piece of equipment that can make the difference between life and death, and the entire process of ejection is a test of a pilot's courage and discipline. Nonetheless, fighter pilots continue to fly and test the limits of aviation, confident that the ejection seat is always there to save their lives in an emergency.
