I enjoy aircraft quite a bit,although not one that's intentionally diving this location,coming down too far w/ full throttle climbs;I would like to learn more about aircraft and I appreciate this feedback.
I suppose this could be an 'experimental' & the pilot might not be licensed.
There is a fair amount of canopy right outside my apt. on the 2nd floor,in season.
The next time this happens with a clear sky,I will walk away from the apt.(across the street)to the other side of L st. where the large PG&E equipment lot is and certainly get a video.
