An F/A 18 Super Hornet solo performance at MCAS Miramar, Oct 2010. This was a humid day, which made for more condensation around the wings.
I've noticed how half the guys on YT think this vapor cone has something to do with the sound barrier. As cool a sight as it is, It doesn't.
Attention Navy/Marines Families:
If you have a loved one deploying out of San Diego, or, even better, a homecoming, that you would like filmed, send me a message at the email below....

I will film and upload to youtube for free.

A super hornet solo performance at MCAS Miramar, Oct 2010. This was a humid day, which made for more condensation around the wings. The technical term for this is the Prandtl--Glauert singularity.
Note, this is not the breaking of the sound barrier. Vapor cones, the Prandtl--Glauert singularity, are associated with a sudden drop of air pressure around the jet, resulting in condensation. It happens at high speeds, and particularly in higher humidity.
Note: The "whoop" sounds starting at 0:48 are not the sound barrier. They are the sounds of the compressed air squeezing out moisture, with about a 1/2 second delay, - the FA-18 was 1/2 mile away as it created this cone effect.
