well everyone seems to make a good point, i dont know if it is or isnt being broken but i think its a good video either way, waha

i cant believe that nobody even believes this.. IT IS NOT FAKE...... a lot of people still cant explain behind the vapor cloud....

rear more of this.

here is some more.

I have seen this video before about a year ago.. it was in a longer video made as a kind of joke music video against all the shit that was going on in the middle east. My ex's dad was in the navy and one of his friend emailed to him telling him to watch when the plane broke the sound barrier.. if it's true of not I personally do not know...but I do know that one of the nave guys that sent it to him said that he was ont he ship, and that is indeed breaking the sound barrier.

 

Its not a fake and he is breaking the sound barrier. This actually used to be a common occurance on aircraft carriers back in the day. Once crews were out to sea for some time and hard at work..the captain would usually have some type of reward or recreation. One of those things was "steel beach". The flight deck would be secured for a day...and you could go up top...run around have a party, do different activities...etc. Another favorite was the sound barrier pass. An aircrew would do a flyby and time the breaking of the barrier so it was infront of the ship. A spectacular sight obviously. A "reward" to the carrier crew.

The concussion of the boom would not kill or hurt anyone from that distance. Most of the energy would be projected fwd anyways. It would be LOUD and it would shake your chest and rattle your eyeballs. But thats about it. Keep in mind...its not an explosion...just a compact wave of energy that is "piling up" in front of the aircraft. Yes...its alot of energy. Many of you have heard the sonic boom from the shuttle decelerating through the atmosphere. Granted...thats at a great distance though.

Last I remember...the Navy stopped this practice for the most part a while back. When I was an aircrewmen in the Marines we had tons of human factors training. One of the lessons depicted this very practice....but on this particular supersonic pass out at sea...the aircraft had a catastrophic engine failure right infront of the carrier. I believe the crew was lost...and the navy stopped the supersonic passes.

BTW....the huge area of condensation forming at and in front of the aircraft usually occurs just before going supersonic...maybe mach .98 or so. Its possible to go supersonic with no huge cloud forming. Its just from the rapid drop in pressure making the water vapor condense.

If you look closely at the video...you can actaully see some areas where the water vapor becomes visible only at the areas where the air is moving faster over some surfaces...such as the wings and canopy. Thats becuase those areas have supersonic airflow moving around them. Then the larger cloud forms in front of the entire aircraft. If the video kept playing...there would be a point where no cloud would be visible...its probably at that point that he is supersonic.

Anyone who has spent alot of time around high performance military aircraft has seen and heard these aircraft flying and maneuvering very close to mach 1 has heard the lesser sound of "whipcracks" as air becomes supersonic or tranasonic over smaller areas like antennea masts or flight control surfaces. You can get alot of that without ever having the actual aircraft go fully supersonic.

I miss the old days being escorted by F/A 18s and then seeing them break off to go dogfight with some Air Farce F16 on practice runs. The "Molakia Run" in Hawaii was always fun. But as a helo crew on CH-46s....we ALWAYS were killed

I also got to witness alot of neat things at MAWTS-1 in Yuma Arizona. The Marines equivelent to Top Gun. There we did Air to air manuevers of Helo VS Helo
Helo Vs fighter
Helo Vs SAM
and a ton of other neat things.

 

 

 

Mach 1 is registered at 742mph. If you look closely the planes afterburners are one. Plus look at when the vapor first starts you can see the precussion hit the water. I think the sonice boom caused tremendous vibration/decible causing the moisture in the air to condense thus all the white puffy mist. What the hell did I just say? I think it's real. -Mark

 

thanks for a very good explanation, hybrid. i myself couldnt really understand it at all till you explained it. thanks
