Seems I've been using wrong terms and confusing language. Sorry, I'm not trying not to be wrong. I guess it came across like that as my language wasn't precise and that made it hard for people to get what I meant. All good now , I think I've got my answers - I was right with the outcome of the concept , just didn't articulate the concept well enough.sophiecentaur said:
Yes, aircraft fly in the sky all the time. I imagine that at some time some airliner has been traveling west at just the right latitude and speed to cancel out Earth's rotation completely. In fact, at 56.5 degrees north or south the Earth's rotational velocity is about 575 mph, which is about the average cruising speed of a typical airliner. Anyone flying west into parts of Denmark, Sweden, or Latvia (or huge areas of Russia) is roughly canceling out Earth's rotational motion.Vic43 said:
What scenario?Vic43 said:
What would be observed looking down at the ground from the aircraft? And I suppose it would have occurred flying east aswell, wht would be observed in this case?Drakkith said:
It seems that you have lived your whole life, secluded in an apartment, without experience of transport in the real world. Do you ever go outside, to catch a train for example?Vic43 said:
You mean like getting rid of the Earth's atmosphere and using a rocket-powered drone?Vic43 said:
Why are you being disrespectful chap? Ofcourse I've experienced transport. I just never seen the earth spin under a stationary craft (relative to a position outside our atmosphere like a star or whatever). If there was a wide train with a clear bottom that had a marker on the track underneath, that was travelling, and you had a drone travelling on the train , you let the drone travel a distance with the train so it was going at the same velocity , then you hovered the drone , it would be still going the same speed as the train , but if you then flew the drone in the opposite direction of travel until you got to the marker on the track and came to a hover over that point, I would assume that the train would then move under the drone?Baluncore said:
Nothing special. It would look like you're flying normally no matter what direction you're flying in.Vic43 said:
Why do you need it to, to understand the math? The math is very simple. An airplane flying flying east to west at the equator at 1,000 mph would see the sun remain stationary in the sky. A plane flying at 500 mph would see the sun move a (1000-500)/1000 = 50% of normal speed. What's the problem?Vic43 said:
It wouldn't though. It would cross from horizon to horizon in 10-20 minutes perhaps, faster than would a normal airliner that doesn't fly at mach 1.4. If it crossed in front of the sun, it would be there only for a few moments.Vic43 said:
As @Halc says, the plane would not appear stationary to you, it would zoom by at high speed and a few seconds later you would hear a sonic boom (if you are at low lattitude where the speed is supersonic).Vic43 said:
As others have pointed out, it would only be in your sky for a few minutes. Your portion of the sky,from east horizon to west horizon is only a few hundred km. The plane will cross that in minutes.Vic43 said:
It wouldn't. You need to draw a diagram. The plane would not be stationary relative to the Sun to a ground observer.Vic43 said:
You're not going to see the plane for all that time. It would have travelled half way round the Earth in that time. You can only see the Sun for 12 hours because it's so far away.Vic43 said:
