No proof standard aircraft is used
No proof all speeds of all jet streams (theirs more than one idiot and they flow in multiple directions)
No speedometer/odometer/altimeter readings
No mechanical inspection of all equipment, instrument on plane that they aren't altered in any way
As planes fly higher the air is thinner, the means they can go faster cause the air is less dense, perhaps they are flying at an higher altitude then they say. The get away with this by claiming they are flying at optimal speed/height – optimal for what – to lie to you?
https://www.quora.com/Do-airplanes-fly-faster-at-higher-altitudes“As altitude increases, air temperature decreases. The speed of sound in air varies directly with temperature, so as temperature decreases, so does the true airspeed associated with a given Mach.
As aircraft climb to the transition zone at a constant indicated airspeed (the speed shown on their instruments), their true airspeed (actual speed through the air) increases. This is because as air gets thinner it has less impact on the sensors that drive the airspeed indicators, so for a given indicated airspeed, true airspeed increases with altitude. So, Yes.”
Dodge more.
The first link in the post you quoted has the proof of the aircraft used, the Boeing 747-400, noted as "B744" on the upcoming flights, and with the tail numbers of the completed flights. But you're not interested in verifiable fact, so who am I kidding. You're already spewing that the airlines are now in on the scheme alongside NASA.
High altitude winds are known to break 100 mph. But even a 100 mph tailwind (assuming you actually have this wind the ENTIRE WAY does not turn a 660 mph cruising speed into a 1027 mph overland speed. And I was using a Google average for flight times. Some of the flights listed in that link are landing after just a 13 hour flight instead of 14:10. So on that particular flight, the aircraft would have had to averaged 1120 mph, close to double its optimal cruising speed. And to answer your question, "optimal" is the term used to note getting to your destination having used the least amount of fuel possible. So optimal air speeds are just the airlines' way of saying "go XXX this fast to get there using the least amount of fuel."
Altered equipment? You really want to cling desperately to an all encompassing conspiracy, don't you? Is this like a defense mechanism for you? A real life manifestation of the backfire effect? It certainly appears to be the case, so no matter how well we all demolish all your bullshit proofs, it will never sink in. Your primitive mind won't allow it. You are intellectually INCAPABLE of accepting criticism.
