There is a thread on another forum where someone found a glitch with the Icon and got it to 140k+ altitude and also achieved the mach 2 and 3. http://msflightforum.myfastforum.org/about243.html

 

The fastest I could get the P51 to was 778 knots at about a 70 degree dive from it's ceiling...you can see the shock wave as you pass Mach 1 which I thought was cool...pretty sure you can't get it to Mach 2 unless there is another glitch somewhere.

would that happen if you have no engines to produce sound?

 

Yup, because, in a similar fashion to the thunder sound from a lightning strike, the sonic boom you hear from an aircraft breaking the 'sound barrier' is caused by a shockwave as the air is rapidly compressed.

I don't know how far an SR-71 would get at Mach 3 from a take-off. I stand to be corrected, but I was under the impression they took off and tanked again from a KC-135 before getting too carried away with the high speed stuff. Of course that could have been because they could, not because they had to.

 

They take off only partially fueled and then meet a tanker because they leak badly on the ground. Once they're in high Mach-number flight, thermal expansion of the skin and airframe seals the fuel tanks.

I thought it (sonic booms) were something to the effect of travelling at the speed of sound AWAY from a ground object, the sound you make would "compound" in such a way that the sound you make at 500 meters away would reach the stationary listener at the same time as the sound you make at, say, 550 meters away, resulting in a loud noise or "boom".

But as I write this, I hit Wikipedia and it looks like I've had my science wrong for a long time....Darn.

 

Yes Superman would create a sonic boom as seen in the latest movie. Do I detect upcoming Alaska DLC? :LMAO:

Not Alaska... the Metropolis DLC is scheduled for October.

Does he have a virtual cockpit?

And TrackXR?

A mile away, my friends, I saw these cracks coming a mile away. :Waiting:

 

I was toying with the idea of mentioning the upcoming release of Wonder Woman's invisible jet and how that VC might be explained away...but I decided not to.

 

All I can say is they'd better hurry up and release Alaska, that'll shut me up for a while!

Man of Steel, sound barrier of Kleenex?

Yeah, they'd better. With all the silliness in this thread, we might all be headed for the booby hatch! :crazy:

Whut?

 

They developed a tailless delta to try it, and gave up when Geoffrey deHavilland jr was killed in it as it disintegrated when approach Mach 1.

 

"In the early 1940s th(e) chain of reasoning led to dire predictions about supersonic flight. Pilots blamed the sonic "bunching up" of air for the frightening vibrations airplanes encountered when they dove at nearly sonic speed. Engineers knew that a wing moving a supersonic speed creates shock waves, violent disturbances in the air which move along with the wing as if attached and, in a sense, adjust the airflow for the supersonic wing's lack of advance warning. These shock waves were expected to ruin the air flow, stall the wings, reverse the control forces, and otherwise produce serious mischief. Numerous incidents of near catastrophic high speed buffeting, control loss and upset encounters, as well as some unexplained crashes, seemed to confirm those fears."

 

"There were serious predictions that the pilot's voice would get stuck in his throat when he flew faster than sound, ignoring the fact that in the cockpit the pilot is surrounded by air at rest with respect to him. Some even feared that flying supersonically reversed time and that the pilot would turn into a young boy."

 

"If you were a sober analyst you would have noted that Geoffrey de Havilland died in a disintegrating D.H. 108 while trying to 'break the sound barrier'. As late as 1959, the Reader's Digest conjured up an 'invisible wall' in digesting an article from The Royal Air Force Flying Review:"

 

"During the war a British engineer named Frank Whittle invented the jet engine, and de Havilland built the first production-type model. He produced a jet plane named Vampire, the first to exceed 500 mph. Then he built the experimental de Havilland DH 108 and released it to young Geoffrey for test. In the first cautious trials the new plane behaved beautifully; but as Geoffrey stepped up the speed he unsuspecting drew closer to an invisible wall in the sky then unknown to anyone, later named the sound barrier, which can destroy a plane not designed to pierce it. One evening he hit the speed of sound, and the plane disintegrated. Young Geoffrey's body was not found for ten days."

There is no way a WW2 fighter should be able to pass Mach 1 intact

 

Surely you do not mean in light of Geoffrey de Havilland's tragic test flight?

And TrackXR?

 

For Superman, that would be TracK LeX L
