|If nothing else, the Cj2 was traveling at a high rate of speed as the end of the runway was looming.
NTSB has stated they know the touch down point but aren't releasing it at this time. As they commented on approach there were no problems reported by the pilot, I'd assume they would have stated the same had the Cj2 touched down without any concerns.
The distance from hitting the sign post, to striking the hangar is about the same distance as the end of the runway - and they slammed into the hangar, leading me to believe they would have gone off the end, or incredibly close if they didn't.
The end of the runway is I believe a 60 foot drop and nothing but houses - the Cj2 was based at Santa Monica and the pilot has been flying out of there for years - so he knows the end of the runway.
They hit the 2nd last hangar, if they'd just missed it, most likely this would be a different outcome.
Officially they have recovered 4 bodies, unofficially they are the owner, his son, his sons girlfriend, and a female employee along with the family Golden Retriever. (NTSB site states 5 fatalities?)
I did hear witnesses state about a tire popping!, with too much speed, the lift dump wouldn't engage, meaning no thrust attentuators, heavy braking could explain a blown tire, and I hear once the brakes on a Cj heat up - they don't work so well.
There is a CVR, so that should help clear up a lot, they landed just as the sun was setting - so they would have had the full glare of the California sun directly in their faces which wouldn't help.
There was also several pilot witnesses - so eventually it'll all be explained - sadly it's the 4 Citation to run off a California runway in recent years, 3 with fatalities - all with owner/pilots.
