Yep.

Ah...Welcome back to the Behemoth Board, Willy...

Did you pass?...

Wrong option, I is doing da other one.

I don't even know what she was on about, I couldn't focus on anything else.

Hmm
Depends on the jet stream/tailwind

Also depends on where you're going. From the Northern Hemisphere to South is quicker because it's downhill all the way. Saves a bit of fuel too coz aeroplane drivers can take their foot of the gas and coast.

I too have wondered about whether a plane should arrive at its destination quicker if it flies counter to the rotation of the planet

I've asked commercial Cathay pilots. They can't answer it.

Check flight times going and return for the same airline and airports.

Solved...It was staring us right in the face the whole time...

Takes an hour longer to fly from Sydney to Perth (against the earth spin) versus Perth to Sydney (with the earth spin) but that is because of the jetstream not shariah physics.

Anyhow, back to the dinosaurs...

They're discovering new dinosaurs all the time...

When I went to school there were only a handful of them...Bronto, Tyranno, Stego, Ptero and a few "fish"...

Now, the barstards are everywhere, a new genus found every other week...

And now, some nutter says they never happened...

Hmm....Genesis credibility. Jesus quoted genesis 23 times, apparently.

"The Lockheed SR-71 Blackbird holds the official Air Speed Record for a manned airbreathing jet aircraft with a speed of 3,530 km/h (2,193 mph)"

If an aircraft travelled at over 300,000 km/h, it would travel through time, perhaps reaching it's destination before it ever took off.

No it won't; not really. Only the wind affects aircraft velocity (that and the route, and the engines etc...), see below.

Pilots are not usually engineers. I know a chap with a PPL who is an electronic engineer, but I doubt he would be able to answer either.

"Speed can be a confusing topic when considered from an aerospace engineering standpoint. For this question, we need to consider two "concepts" of speed. The first is the speed of an object through space, which we will consider as the speed of the Earth's rotation about its axis. If we consider this concept, then you, sitting at your computer, are probably traveling somewhere around 735 mph (1,183 km/h) through space, depending on your location relative to the equator (are you wearing your safety helmet?). The second concept of speed is an object's speed relative to the Earth's surface. In this case, you, sitting at your computer, are traveling at 0 mph relative to the Earth. Now let us consider what would happen if you suddenly stood up and started running (run Forrest, run). No matter which direction you run, your speed relative to the Earth would be 10 mph (16 km/h) or so (80 mph if you are a Cheetah). If you were running to the west, against the Earth's rotation, then your speed through space would be 725 mph (1,166 km/h). Of course, if you ran the opposite way, it would be 745 mph (1,199 km/h). Your speed relative to the Earth is the same no matter which way you run. It isn't affected by the rotation of the Earth.

Aircraft take off from the surface of the rotating solid spheroid (i.e.: the Earth) at the speed of rotation (i.e.: your 1,675 km/h). Aircraft then move in the fluid at a velocity relative to this rotation.
If an aircraft travelling faster than this rotation (e.g.: a Lockheed SR-71 Blackbird) flew East to West from point A at sunset at the speed of the Earth's rotation, the pilot would continue to see sunset until their speed increased or decreased.
If you (as the pilot) increased your speed to be faster than that of the Earth's rotation, you would watch sunset "reverse" before your eyes - if 100 years ago there was a solar powered British Imperial RAF Supersonic Aircraft, the pilot could indeed watch the sun never set across the Empire.

If this aircraft travelled from Mecca to Peking at at sunset at the speed of the Earth's rotation, West to East well, you'd see sunrise twice as soon as if the plane never took off. It'll still take the same amount of time to get to Peking, because the distance between those two points on the surface is the same, and the Earth's atmosphere does not freely rotate around the surface like a wheel on an axle, it's locked to it. Unless you travelled at 11km/h up to orbit, and then down again, thus leaving the Earth's atmosphere-surface system and rejoining it; or maybe accelerating to 300,000 km/h, and folding spacetime, you would not be doing anything other than moving towards your destination at the same rate as any destination at the same range in any direction.

The atmosphere is a fluid, surrounding the solid spheroid, but the rotation of the atmosphere as a whole (i.e.: as driven by the friction on the Earth's irregular surface) is negligible: the atmosphere is locked to the Earth (more or less). Winds are largely a result of heat exchange between the surface and atmosphere, which also varies with the kind of of surface - mainly oceans and land, and mountains on it. The atmosphere also contains layers of differing viscosities, and there's a staggered dragging of the layers of air around the Earth that is rendered uneven due to the uneven surface of the Earth, and variations of heat and gravity around the Earth.

As a sphere, it's motion is also more pronounced at the equator than the poles (rotation speed also varies with latitude), and in fact the 1,669-1,675 km/h (1,000 mph) is the equatorial angular speed (you can approximate the speed at your latitude, by doing 1,000 mph times Cos (latitude in degrees and decimal minutes).
Due to the variability of the surface (seas and mountains etc..), you don't get an even West to East rotation of atmosphere: the dynamics are more complex, and are influenced by the Earth's heat exchange system (e.g.: things like El Nino).
High altitude high-velocity "rivers of wind" like the Jet Stream, can be used to speed up travel time, but they are not limited to simply West to East.

In addition the density of the atmosphere varies with altitude - planes fly high to save fuel because of lower resistence (a bit like how electricity voltage is stepped up to transmit electrical energy over longer distances with lower percentage resistance losses), and hitch a ride on high altitude currents, or avoid areas of frequent higher risk weather events.

Aircraft don't get an speed advantage from the Earth's rotation, either way, because they are locked within the Earth solid-fluid system (the displacement in space between two locations on the surface of the solid does not change; the atmosphere does not (really) rotate around the solid like a conveyer belt; only the winds vary, and an aircraft can use them to vary travel times.
Space Launch Vehicle, on the other hand, do get an advantage from being launched from West to East, because they are leaving the Earth solid-fluid system, and entering orbit, where rotation of the whole Earth solid-fluid system is a separate entity from an object separated from it by the vacuum of space, where only forces like gravity are relevant.

I think that about covers it.

There might be one or two typos or unfinished sentences, but that's 'cos I'm being distracted by a cackling Siamese hag! .

I think you mean Km/s. Time itself would also stop on that aircraft so they would not even be able to serve the inflight meals.

Last year I got a flight to Sydney and we rolled down the runway just a moment after the sun set. As the aircraft rose into the sky the sun reappeared over the horizon, rising up until it was completely above the horizon and then slowly set again. That was cool that was!
