This was not a physical sighting. It was observed in a Doppler radar return

I’ve seen many easily explained radar anomalies over the years but never a huge rectangle with a clearly defined vapor shock wave and trail.
Not birds. Not insects. Not clouds. Judging by the image size, rectangle would be approximately 20 miles in length.

Compressed vapor trail appears to be in excess of 150 miles long.
If anyone can offer a logical explanation of this image, please share.
