Or possibly the tyre marks are from the car that was pushed sideways before flipping over, rather than from the aircraft?

Having said that, the marks appear a little too far apart to match with the car, and the car would have to have been parked quite a way from the kerb to leave those marks.

Dude was arrested for domestic violence just hours earlier when witnesses who saw him physically beating his wife on the side of the road called police. Punched her. Head-butted her repeatedly in the face. 2nd arrest for domestic violence within 6 months. Around midnight after making bail was escorted by police to his own home around midnight to get some things, after which he goes to the airport, fires up the plane, and proceeds to crash it into the house where his wife was sleeping.

Yet some question if wife-beating, Kamikaze Rhedd really meant to do any harm?

Wow.

Doubt it was suicide as it doesn't fit the control freak/narcissistic personality.

I reckon he just tried to exert his authority by trying to scare her with a loud low pass and completely f-d it up. What a waste of a totally good aircraft.

Attempted murder-suicide as his career would pretty much have been over or should be anyway after the arrest.

Anyone seen any security cam video from this apparently affluent neighbourhood? Usually they're thick as flies these days.

Here's one.

You'll have to scroll down to the second video in that link.

I think that clears up a few things, such as this was no screwed up low pass, and it wasn't pancaked in. It was definately a well aimed kamikaze attack with only one possible outcome. I imagine the video makes it look a bit faster than it probably was since there is nothing to gauge size and distance from which to judge the speed..

In the nineties I worked as an investigator for defense attorneys. I may have that bias you suggest in your post. It might look like empathy, it isn’t. I learned one basic thing. It is impossible (for me anyway) to read a mature human being as to intent. I worked on some fascinating homicides; none of them were obvious at the outset. Knowing that, it became a project of research and data.

As a pilot, the plane’s configuration is interesting. Did he leave the gear down after launch from Spanish Fork? Was he just distracted, upset, or focused? Why the flaps? These questions come up naturally; forming an immediate conclusion is never productive. Was reported they had been drinking. That makes the case even more resistant to “intuition”.

I thought the Press report was satisfactory, the video was pure luck, though more a sign of the times than good neighborhood planning.

Pukin’ dog, I used the word “possibility”. Did you miss that? Your post suggests to me that you might have this thing all figured out. That so?

Sorry Dog. Yeah, lots of people use “pine” to mean softwood in general. Got it.

From the video, I see three discrete nav lights flashes. It suggests two things, and since my comments are gratis, I have no worry about offering a cash refund if my comment is in the weeds.

The aircraft “dove steeply” into the home. I estimate the velocity at 120 knots.

Actually, in the home-security video, what I see is the plane (well, its beacon or wing strobes) flying in a nearly flat trajectory at or below tree-top level (compare strobes to trees illuminated by explosion). With about an ~80-foot/25m dive in the last moments. Something (houses, trees) hides the final beacon flash. I think the speed may be a bit faster than 120, but not much.

A bit more about the impact with the garage across the street - video also shows left wingtip damage (briefly): https://fox13now.com/2018/08/13/pays...eighbors-home/

It'll be interesting to see just how much of a technical report the NTSB issues, given the rather obvious "cause" - intentional pilot action. But maybe, if only to sort out the intentional-crash vs. stalled-flyby question.

I don't put a lot of weight on the "his career was already ended by the assault charges" argument - making an intentional successful low pass would still mean he was ending his career.

Respect, 120 knots is 138 mph. The “dive” could be a Stall. But I see it as you do, except any wingtip contact with the house across the street puts the heading rather too far right? The damage to the roof looks very much like the gear went through the structure. Construction detail. The roof is framed not with rafters, but “purlins” ninety degrees relative to standard rafters. It is possible the framework is “applied purlins” to support the outlook. Purlins in that design would be a rarity, imo.

This gives great longitudinal strength to the roof against damage in the direction of the aircraft. Do you see where the skidmarks show a change in direction to the right, suggesting the contact with the auto imparted a rotation in that direction?
Or, at least an impediment to continued forward scrub?

A local news source, Deseret News, lists the house address as 584 E Canyon Road in Payson Utah. Deseret News Story
Zillow.com (a widely used real estate site) asserts that the home at that address was built in 2016. Zillow listing for incident house
The new build may account for the fact that neither Google StreetView nor Bing Birdseye show the incident home. But they do have overhead photography (commonly mislabeled as satellite).
From the overhead photography, it appears that the distance from the landing gear damage to the garage roof line across the street to the witness mark from landing gear on the street is just under 80 feet. If one knew the elevation difference between the garage roofline and the street at that point, one would have the descent angle at impact. I'll hazard a round number guess of 10 feet.
Were 10 feet and 80 feet correct (neither is), this would give a 12.5 percent grade, or a 7.2 degree angle of descent.

Possibly landing gear and flaps were extended to allow a steeper stable glide slope than flight idle would provide, or to allow the more precision control a somewhat higher power setting would give.
I suspect my 10 foot round number guess is a bit low, as the garage has a window at the peak, and the damage is only a little below the peak. Also the distance appears a bit less 80, but not less than 75 feet. So possibly up to an 8 degree angle, but not much more.

I am neither a pilot nor a forensic investigator, and am more trying to suggest a path to an answer on this point than to provide the proper answer.

Hi archae86. I made a wag (wild ass guess) earlier without giving it much thought, and posted ten degrees. I think your method and result is more accurate, and pattern is full’s early estimate of 80feet gable to skidmarks jives with yours.

rgds.

archae.
on my GE it’s down as 1200 S. if you look on street view from the Nebo Loop Road/S Payson Canyon, the house is in the process of construction. You can get a good idea of the approach angle as he went under the power lines, but hit the single storey house.
On imaps it’s down as Rhedd’s Tint & Trim.
