Uh no, I mean uh from what I've seen on the video uh that you can find on social media is that they had some type of engine failure.
And you know, it's a single engine aircraft, so
You lose that.
You have essentially uh think of Sully on the Hudson, right?
You've got one chance to land that thing if you can't restart the engine.
And they were in a altitude and um airspeed profile that really wasn't favorable to successfully landing.
Exactly.
Uh technically he's correct if you have a antiseptic uh scene, you know, with no wires, no obstacles on the ground, um depends on exactly how high they were flying and the airspeed, which I I can't tell from the video, but you know, there's what we call the height velocity diagram, otherwise known as the dead man's curve.
Which is for a helicopter, especially a single engine helicopter, uh, your height above the ground and your airspeed fall within an envelope where the aircraft is capable of maintaining rotor RPM to do what's called an auto rotation and, you know, land successful successfully on the ground.
In this case it looked like they were
So you go d you bring the
You descend quickly in what's called the auto-rotational aerodynamic phase, which the air blows up through the rotor, spins it, keeps it within the operating RPM.
When you get to the very bottom, you know, depending on the aircraft type, could be fifty feet, twenty-five feet, seventy-five feet, uh, you you apply cushion, you know, you apply collective, and that cushions the landing and you and you land.
So you got one shot at that.
And, you know, it's if you wait too long in the diagnosis, which, you know, it takes, you know, a brief half second or so to realize that you have indeed lost an engine.
and look for a landing area, which, you know, they were focused on their job, you know, doing the the electronic news gathering.
So, you know, the pilot, you know, had his his attention mostly on uh focusing the the camera on the scene.
So then what you hear is the audio of the rotor system starting to decay as the engine fails and then the alarm the alarm goes off.
You know, that lets him know what he's gotta do.
But now he's still got to look outside the window, find a landing area and successfully put the aircraft in that position, which
