I agree that the ground features in the DOW-UAP-PR090 footage looks like canal-irrigated areas of Egypt.

But what would a US drone be doing over Egypt, particularly the Nile delta?
Egypt has a competent air force and operates a number of different drone types, some locally produced, others from USA and China.

It has substantial numbers of reasonably modern aircraft and ground-based air defence systems, a hypothetical uninvited Predator-type drone might not last long over the Egyptian heartland.

Circumstantially, I feel Iraq, possibly Iran might be more likely locations.
