Brazil’s electric grid is crazy inefficient too (due to rampant political corruption), which makes electricity very expensive.

“GPS is also the technology that autonomous vehicles will use to report their location back to any number of possible organizations...”

“Everyone knows that an object in a vacuum accelerates at 32 feet per second squared (ft/s²).

What you say makes sense except one helicopter is not pulling the other. It’s carrying it.

“Why are we keeping this legacy device around?”

It had the only working thrust reverser, with engine number two failed. Engines one and four don't have reversers.

Except in flight test:

Agreed. That was a bogus statement.

It’s also required to carry equipment to keep everything cool. See the air intake at the back?

Tin foil? Do you have any idea how hard it is to find tin foil these days?

No. It can electronically scan +\- 60° from it’s center, and the center can be mechanically moved 40° around the nose. At any one moment it can see +\- 120°. With mechanical help the combined field of view is +\- 200°

What’s basic is the physics and the geometry. If you beam the radar you hide in the ground return. There is no getting around that.

The number of engines really has little to do with range. It's more of an issue pertaining to size, weight, complexity, and statistical reliability.

No RF energy runs between the base and the rotating part. It's a pure electrical connection. The RF is actively generated by each of a few thousand emitters on the face of the antenna.

I’m not sure what you’re talking about. We don’t steer airplanes with engines. We have flight control surfaces for that.

I’m glad you didn’t try the slide, but that’s completely irrelevant to this incident.

“I don’t have $800 up front normally for a phone.”

Huh?

The wind didn’t come to picking up a 747. It just lifted the nose, which is relatively light, as mentioned elsewhere is this thread, because the plane is balanced close to its main gear. The fact that the airplane weighs 170 tons is irrelevant.

“U-2 pilots have a small margin of space to effectively land the plane without causing damage to the aircraft.”
