it is interesting to note that Glenn is shooting at a very low DPI (72) which makes this image difficult to enhance or do much forensic evaluation on.

Plus- notice the focus distance to the object is 81 meters (approximately 240 feet) and not infinity - indicating the object is not very large or flying very high. The blurred movement also indicates that the object was either moving very fast or relatively-fast in relation to the camera.

if it is a real craft - and not a hoax- its small - like a mini UAV - maybe used for recon at our favorite non-existent air base.

My guess Glenn is sitting back chuckling to himself about every one's (including my) speculations.

Just not enough data here.
