By the rate of Doppler change that those signals come back, we can actually gauge the speed of that aircraft.
Some of the things that I witnessed that were very interesting about radar is that we would be able to track aircraft all the way down to the ground. And I do mean all the way down to the ground at distances of around 100 miles.
And now that I know the calculation of curvature, 100 miles is 6,666 feet of curvature, of drop. That is literally impossible because radar works at microwave frequencies, two to six gigahertz or even higher, anywhere in the microwave spectrum, and it is absolutely reliant on it being line of sight. Meaning, if you can’t see it, it doesn’t work.
When you take into consideration that we’re able to track aircraft from whatever altitude they’re coming in at all the way down to the ground at a target 100 miles away, and knowing that that target should be 6,000 plus feet below the curvature, that kind of eliminates the ball model.
(check the Earth Curvatur Calculator here yourself)
Well, you know, in air traffic control they have two different types of radar. There’s short-range, airport-based radar that goes out to 60 miles. And then for the long flights, high altitude, and off the coast, they use en-route radar and it can go out to 200 miles. So they can detect targets 200 miles away.
So with radar, the point is that it has to be able to have a direct line to the airplane. With regards to the shape of the Earth, I never thought about it as I worked for 24 years. You don’t say, “Wait a minute, I think that target is too low for me to see at that distance.” Nobody ever even thinks about that.
But in reality, now knowing what must be if we live on a ball, the fact is that at even just 180 miles, any airplane below 26,000 feet — if the radar can see it, the Earth is not a ball. Period. End of story.
And does that happen very often? A thousand times plus a day. A thousand times plus a day somebody calls up, somebody comes from offshore.
There’s a whole class of aircraft that are not pressurized. They can’t fly above 11,000 feet or the pilot will pass out. So they operate at and below 10,000 feet, no matter what. No matter what the weather is, they just can’t operate up there. And there are hundreds of thousands, if not millions, of these airplanes still operating all the time.
So they’d be coming in at 6,000, 7,000, or 8,000 feet from somewhere like Bermuda or beyond, say 180 miles from Miami. And I say, “Roger.” And every time they do that, they prove the Earth is flat — and they don’t know it. But it’s absolute undeniable proof.
At 180 miles the number would be 26,000 feet, and at 200 miles about 29,000. A lot of commercial flights are never at 29,000 feet when coming in from 200 miles out. So over and over again.
