davidsyes's Journal: Drone Surveillance over Glen Park-Mission District?

Lately, over the past few months, I've been tiring of the constant buzz-saw/RC-plane-like drone running aerially from about 11 PM to past 2AM. I used to think it was out-of-permit work after hours. But, last night, having had enough, I spied the skies.

I watched commercial and maybe private aircraft fly over the Glen Park BART station. I let my ears guide my eyes. I noticed a craft hovering pretty much stationary over highway 280 near the BART station. That annoying fucking buzz sound may not be disturbing the residents near the freeway, but up the slope of the hill that buzzing-droning is goddamn annoying. I have to sleep with earplugs or don headphone with music cranked up.

I can even hear it change altitude, indicated by spikes and drops in decibels of sound, dips and rises probably instigated by thermal currents.

Why is this drone there? I suspect it is not an acoustics drone, but one relaying police the signals or thermals of gang activity or suspicious activity that triggers telemetry gear, such as gunshot locators mounted atop telephone or power or lighting poles, or in dead-drop observation vehicles parked around the Mission District area.

I WISH they'd replace that noisy predator or whatever it is with something quieter!
