Did anyone observe the small plane flying low last night? We saw it first while dining at Havana about 6:30pm and then again around 9:30pm over our home in Duval. It made several passes, so I turned on an app I have (Flightradar24) and tracked the plane. It made several passes from north to south in a striped pattern. Not sure if the picture will work but the white lines show the flight path. I wonder if they were spraying for insects or something.
