I just heard that the debis field for the Chinese balloon is an area that is 15 football fields by 15 football fields. I guess that means a rectangle containing 225 football fields. I had no idea how to visualize that, so I did a bit of figuring.
a football field is 57,600 sq ft or 1.32 acres.
So 225 of those suckers would be about a half of a square mile or about 300 acres (not to put too fine a point on it).
Another story said that the field is 7 miles long. That would make it about 0.07 miles, or about 370 feet wide.
That doesn’t seem overwhelmly big, but the papers ignore that we are dealing with a volume instead of an area. Apparently the water is about 50 feet deep, and debris could be suspended at any depth, so the task may be a big one.
In any event, I don’t think that football field units make a lot of sense here.
