I've been underneath a Blue Angel at full boggie that routinely flew 50 to 100' over my house during the Seattle Seafair shows. It mad a small pine tree that was below the level of my head in my neighbors yard shake from the sound. The best I can describe the sound was like the sound of a sheet being ripped amplified about 100,000 times. It physically hurt your heavy organs!
An F-16 probably wasn't what she "didn't" hear, if it was anything at all!!
