What's up with the zigzag on this Hawaiian Airlines flight?

Any knowledge on this? I’m flying on this plane tomorrow and it’s making me just a hair apprehensive :blush:

Generally means that there has been a stale (in the past) position received and the usual filtering didn’t catch it - so the position snaps back to an earlier position briefly. It’s a data error rather than anything real.
