Anyone know what direction they were going in relation to where it came to rest?
They were west bound until what ever happened, happened to them. The direction that the wreckage is now facing would be north, requiring at least a 90 degree turn to the right.
A relative large airfield was 2.5 miles due south of the accident site, Wiley Post Airport (KPWA). Although Wiley Post is a controlled airport, the tower was closed, it does not open until 06:00.
For those that are seemingly focusing on an O2 fire in the cabin, I would caution you that there is no confirmation that there was a fire in the cabin. Two other witnesses have come forward and neither of them reported seeing such.
