Is his flight path, in a big 'Z' line normal?

It appears to due to a data entry glitch. If you click on the
"Status En Route (No recent position)" link you will see the position
log:

It would appear that the longitude entry for 7:28PM has a type: it says
-137.50 but clearly should have been -127.50.

A careful examination of the flight log shows minute-by-minute updates
up to 6:34PM and then roughly hourly after that. According to Google
Earth, the position at 6:34PM was a distance of about 200 miles from the
California coast. Which is consistent with what I understand is typical
ATC radar coverage range - perhaps someone who has more knowledge of the
subject can confirm or correct that.
