Sonic Booms and UFOs in Granbury

We have two strange reports coming out of Granbury, TX (outside Dallas/Fort Worth). The first is from April 27th. According to a MUFON report, a craft of some kind was flying in low Earth orbit and then exited the atmosphere.

an object, white no blinking lights was moving from north to south at an unknown altitude (probably 20000 ft) moved in a strait line then faded from sight in a clearly marked leaving the earths atmosphere pattern. This was a clear case of a vehicle leaving the planet, it was in the area of sky dominated by the orion constellation. as I reiterate it was plain that this object was definitely leaving the planets atmosphere. there was an airplane in the vicinity but I don't think it was connected in any way since that plane was probably at about 8-10 thousand feet

Then a couple of days later, on April 30th, residents of Granbury - and Johnson and Hood County at largeheard unmistakable sonic booms! This reminds us of the phenomenon that's taken the world by storm - the strange booms and rattles being heard all over, including San Antonio and Dallas. (1, 2, 3) Lightsinthetexassky.blogspot.com has collected some amazing "ear"-witness reports:

"I actually saw the sonic air wave disturbance, with this one. You know how everything is distorted slightly in a circular pattern around a blast, as the percussion waves push outward. You can see that in video clips of massive explosions. I saw that today. Just as the blast wave hit us, everything became completely out of focus, a split second after the booms. We thought the giant cottonwood tree was going to fall on us. The tree was swaying back and forth, and over a dozen branches came crashing down all around us. I have storm glass through out the house, since the last boom we had. I know that there are broken windows all over Granbury today. We heard many, many police sirens right after the boom as well."

This event seems to have affected other cities in Johnson and Hood County, as well. Someone on Google was also searching for info regarding a sonic boom in Dallas the same night.
