So, is it going 800 mph or 500?

It's speed relative to the ground was 800 mph. (Groundspeed.)

It's speed relative the the air it was flying in is around 560 mph. (Airspeed.)
The jet stream (air) it was in was moving east in excess of 200 mph.

Simple.

What I was getting at is, what do pilots use?

I would think ground speed because the whole point is getting from ground point A to ground point B?
