Not 1957 but 1958 which is close enough.

It was in production in 57 with a live test shot in 1957.

They do but then they take a big expensive ship find the cable and bring it to the surface to fix it.
The real issue is not if it is possible because it is possible. The big question is if it is worth it?
Removing all the 02 mean no fires and reduced corrosion.
It also means more cost for fixing thing that go wrong.
The simplest way to do this would be to flood the bunker with Argon since it heavier than O2 and N2 it should displace the O2 but again the question would be why?

Or how about having the array swap in spares.
Every few weeks or so one of the spares could start to act as a mirror of an active drive and once that drive is mirrored you swap the active drive to the spare and the spare to the active?

The phased array will have to be even larger than the dish to get the same beam size.

Simple answer is you take them to court for not paying but do it now while the merger is in the works.
I really hope that this merger fails like the TMobile AT&T merger did but since the current president does not need to get reelected I have little hope.
He is hoping his legacy will be opening Cuba.

And with a 3 meter dish at 300mhz you are have a several degree beam. At 300 meters that is a big stinking beam. At the 4 db contour your at around 25degs beam.
It is simply too dangerous and impractical of a solution.

Might I add that reading magazines like Car and Driver, Motorcycle, or any other graphics/photo heavy reading material is much nicer on a large tablet.

And the power needed at 100 meters?
How about at 300 meters?

Wrong. Metal is not the only thing that returns RF.

To Jam maybe but a jamming is not "frying" and a jammed drone does not really help a lot because it is just out of control at that point.
You also have the issue of size so unless you want a massive radar set on top of the white house you are not going to fry anything and it would be bad to start with.
Even if you had a perfect detection system then what? The interception is the problem. Not even hitting it but not hurting anyone that is standing around.

Simple. A radio controlled quad copter would have about the same RCS as a bird and fly at about the same speed. To burn out the electronics you would put just about everyone around the Whitehouse in danger of being hurt. If it was a weaponized rc quadcopter you could blow it up over innocent people if it had not crossed the fence.
In other words too many false positives as far as the frying the electronics too much risk of collateral damage. The amount of power to fry a quadcopter would be high enough to do some real harm to people.

Trust me, Chuck Schumer knows exactly what he's doing. He never passes up an opportunity to restrict freedom.

THIS^^

These leaders that are supposed to be representing the peoples' will, seem to be so disconnected from what we the people want.

I think a larger problem is these asshats making this a lifetime career.

I know it stands a snowballs chance in hell, but we desperately need term limits to keep fresh blood more representative of the citizenry going through up there on a regular basis. These govt jobs were NOT meant to be lifetime careers.

Maybe more of a chance of governmental representatives thinking more of the rights of the people over the ever growing power of the govt to restrict the commoners' rights.

No but you could be pretty sure that someone with an RC aircraft in the zone should not have one.

Better Radar?
Let me guess, you have a degree in liberal arts.
