[FairfieldLife] Warplanes in the Skies of SF

[jr_...@yahoo.com [FairfieldLife]]

I've heard these loud supersonic planes for the past few days and wondered why 
they're so loud.  Did they lower the elevation of the approach to the airport 
for commercial airplanes?  But, no, I realized that there must be a military 
air show this weekend as part of the Columbus Day celebration on October 12, 
2015.
