What is the minimum speed someone would have to fly in a westerly direction (the opposite direction of east) to get to their westerly destination if the earth is rotating eastwardly at about 1,000 miles per hour?

if the earth really is moving 1000 miles per hour. you could never fly to the opposite direction.
just think with yuor senses and logic. if its 20meters per second winds outside, its reaaally windy, you can barely be outside. now imagine 1000 miles per hour, yet here we are, no problem. it would make earthquakes look like pleasant surprises

It is kind of complicated. I did a google on that question and it was a bit complex. At 1 MPH plane speed with 1000 MPH eastward rotation of the earth the plane is actually moving east 1 MPH slower than the rotation therefore gaining forward westward momentum. Or something like that. Unfortunately, I'm not an aeronautical engineer to offer a more coherent explanation.
I shouldn't have to explain this, but since certain persons don't understand basic physics, I will...
The atmosphere and water, and all fluids, and solids suspended in air or fluid such as balloons, planes, fish, etc., move along with the Earth's surface. Gravity holds them in sync with the Earth's rotation. Here's an illustration:
A car with driver and passenger is travelling at 100 kilometres per hour (~60 mph). Inside the car, the driver picks a penny from the console and lobs it over to the passenger. Does the penny suddenly travel "backwards" in the car at 100 Km/h? No. It continues to travel at the same speed as the car, and lands in the passenger's outstretched hand.
Similarly, a helicopter takes off vertically. The Earth doesn't suddenly "start" moving at 1000 mph beneath it, because the helicopter is moving at the same speed and direction as the Earth beneath. Unless there is a wind, the atmosphere is doing the same thing.
A plane takes off (in any direction) and gets to its cruising speed/altitude. Its airspeed relative to the ground is not 1000 mph plus or minus anything; it is simply the speed relative to the ground, which is almost entirely due to the propulsion of the airplane itself, not due to the ground moving beneath it.
People, this is rocket science, but it's the easy part.

You mean if I jump straight up in the air, I will not land a few feet, yards, or miles away from where I jumped? Oh noes!!!
