Saw this photo on Bing this morning and found it extremely interesting. It's of a US Navy F/A-18F Super Hornet creating a sonic boom. "The halo of white appearing around the Super Hornet is condensed water droplets in the air, pushed together as the air around the jet rushes past the craft, creating the shockwave in the atmosphere that will result in the explosive sound we call a sonic boom. Because the jet is traveling faster than sound, spectators on the ground will see the jet before they hear its engines or the sonic boom it’s producing." - bing.com
Wonderful shot Mal. The love of my life is the Typhoon. That very distinctive sound makes your blood tingle and stops you dead in your tracks. To see it perform is truly a sight worth seeing
