Oh My Goatse! Yew brokkin' Mah Saund Barryer!!
>> Crooked Truth
correct me if im wrong
but that cloud is because water vapor is being condensed by the air pressure that is caused by breaking the sound barrier
right??

Mostly right. The condensation is not due to pressure, but rather to a vacuum effect. Simply put, the airplane's moving too fast for air to fill in in the shockwaves that it creates, so the water vapor condenses, creating the cloud that you see in OP's pic and mine..

heres another good one i have

those last two aren't breaking the sound barrier, they are contrails caused by high speed banking and such

actually they aren't necessarily

>>421431
since a vacuum by definition involves low pressure, the two are interrelated.

Generally speaking yes, but it DOES NOT have to take place at a supersonic speed. It occurs when airflow over a part of the wing is supersonic and still subsonic at other parts (also referred to as transonic), which (by design of a wing) occurs before the speed of the whole plane is supersonic. The vapor occurs when the local pressure drops suddenly and depresses the air temperature below the dewpoint, essentially forming a cloud. It's referred to scientifically as the Prandtl-Glauert singularity.
