Explanation: Is this what a sonic boom looks like? When an airplane travels at a speed faster than sound, density waves of sound emitted by the plane cannot precede the plane, and so accumulate in a cone behind the plane. When this shock wave passes, a listener hears all at once the sound emitted over a longer period: a sonic boom. As a plane accelerates to just break the sound barrier, however, an unusual cloud might form. The origin of this cloud is still debated. A leading theory is that a drop in air pressure at the plane described by the Prandtl-Glauert Singularity occurs so that moist air condenses there to form water droplets. Above, an F/A-18 Hornet was photographed just as it broke the sound barrier. Large meteors and the space shuttle frequently produce audible sonic booms before they are slowed below sound speed by the Earth's atmosphere.

Here's some Information on the record black bear killed in Monroe County, Pennsylvania this season.
This bear was shot with a crossbow.
He weighed in at 875 lbs. live weight and 744 lbs. dressed out.
He was the second largest black bear ever killed in the world; missing the record by a scant 4 lbs.
This alligator was found between Lakeland and Winter Haven Florida near the house of Anita and Charlie Rogers, who could hear the beast bellowing in the night.
Their neighbors had been telling them that they had seen a mammoth alligator in the waterway that runs behind their house, but they dismissed the stories as exaggerations. ‘I didn’t believe it,’ Charles Rogers said, but after the alligator was killed, they realized the stories were, if anything, understated.
Game wardens were forced to shoot the alligator. Joe Goff, a 6’5″ tall game warden, shown below, walks past the 28-foot, 1-inch long alligator that he helped shoot and kill in the Rogers’ back yard.
