I have a chunk of work to do this afternoon, but I'm hoping I can sneak in some time to read all of these:

Finally, after complaints up and down the lakefront that the US Air Force Thunderbirds caused a sonic boom during Chicago Air and Water Show practice on Friday, University of Illinois aeronautics professor Matthew Clarke says that while none of the F-16s appear to have exceeded Mach 1, he is confident that part of one of the planes did. “Even though the global flow may not be faster than the speed of sound, there are places locally faster than the speed of sound, creating shock waves,” he said. “While I can’t say that the whole plane went supersonic, I can say — from the video — shock waves [were created] from parts of the aircraft.” The mini-sonic boom broke the lobby windows of four Lakeview high-rises but caused no significant injuries.

Also: I am beyond overjoyed that the National Weather Service predicts dewpoints below 18°C by Wednesday and below 15°C by Saturday. We have had the most uncomfortable summer that I can remember, with dewpoints at Inner Drive Technology WHQ lingering above 20°C since 10:30 Friday morning after a very brief respite on Thursday. If I have time this week, I'm going to analyze the data to see exactly how humid it's been here lately. But this prediction is delightful:
