I hope you are aware of the tremendous amount of noise being generated by SJC takeoffs over Santa Clara. This is the Northflow noise, which happens as long as weather is nice (most of the year), but there hasn’t been much attention paid to the issue yet. SJC’s annual passenger count went up to 15M, and then added tens of new gates in June. Since then the number of flights taking off over Santa Clara has exploded. I am writing this as about 20 takeoffs have happened within 15 seconds of each other. It is impossible for me to even open my windows.
