Horizon Air Dash 8 making many circles from Seattle


Senior Member.
Interesting flight path here. What was this plane doing? Was it performing some kind of test? Testing navigational instruments maybe?
The plane is Horizon Air N410QX, a Bombardier Dash 8. This is a twin-engine turboprop plane that can carry 78 passengers.

I'm a little confused as to how you found that. It's there in PF if you use a direct link:
https://planefinder.net/flight/N410QX/time/2015-10-14T18:45:25 UTC/speed/1
But I can't see the actual plane flying. Is there a playback link that shows it actually in the air?

I looked it up in FR24 (with their new KML download), and at 2015-10-14 18:45 UTC it was apparently on a scheduled flight from Redmond to Seattle. It did do a two lap hold over Portland though:

It seems to be some glitch in the planefinder data. At 18:44:59 UTC the plane is nowhere. At 18:45:00 it appears with the complex path in the OP.

BTW I was trying to identify the flights in this video:

What Mick found at flightradar24 matches those looped paths well.
