Like a valve.

A valve.

It's the thing that opens the valve.

Or even a light.

So the concept is that you are now separated.

There is no direct connection other than electrical from what you're pressing to what happens at the far end.

That gives you amazing ability to interfere or intercept that signal and add value to it or to modify it.

So in terms of aircraft, what the pilots do with the thrust levers and the side stick,

They are inputs into computers that massage them.

If the computers think you're not doing the right thing, they might even override it.

The computers in an F-16, F-22, F-35, if the pilots don't avoid the ground, and these fighter aircraft are meant to be close to the ground, but if the computer thinks they're going to hit the ground, the computer interferes, takes over and pulls them away from the ground.

It's an override.

Maybe the pilots in Ukraine turned that override off when they started flying F-16s in Ukraine.

A lot of F-16s were crashing from pilots, particularly in F-16s.

They'd pull so much G that the blood wouldn't get to the head, they'd blackout.

And if they're close to the ground, they'd die.

So when they put in this software to...

predict whether they'd hit the ground and to stop them hitting the ground or to get to a safe place, all the deaths from accidental flying into terrain virtually stopped.

And that is now accepted software through all the fighters in America.

The pilots agree that that intervention is actually very good.
