The plane that burned into the ice on the St Louis river near the swing bridge in Duluth MN was flown by a design engineer for Cirrus.  He helped design the Cirrus jet.  

https://www.fox21online.com/2023/02/24/pilot-who-crashed-into-st-louis-river-was-cirrus-design-engineer/





"According to David’s brother, Daniel, he was a “brilliant” design engineer for Cirrus Aircraft in Duluth.

“David was instrumental in the design of the Cirrus single engine private jet that recently won the coveted “Collier Aviation” award,” Daniel said in a social media post."


Looks like it was a Cirrus GTS carbon SR22.

I wonder if one of those ballistic parachutes would have helped in that scenario. I'm not an aviation guy, though.

I think he was too fast and too low.

Looks like he was heading for the Superior airport and burned in on the way.

Everything I am finding, it looks like he was around 152 before the track ends.  At one point he was doing 180.

Mostly those are pretty new, with low time engines under 200hr. One of my family members just got a new SR22 right around the same time Cirrus grounded their own fleet.

Somewhere I have pictures of my boys in a Cirrus Vision jet when people were still screaming "Vapor ware" at me for posting the pics.  

That is a cool plane.

If planes were the only transportation available, most people would only be able to walk.  

Of those who were able to fly, many would find that 3rd axis problematic at best.

I don't know if he was on fire or not.  


Smoke in the cockpit is possible.  But I would think he may have mentioned that to ATC if that was the case.  



This was the result of smoke in the cockpit.

The last 600 ft of descent was at -1161 fpm avg, for 31 seconds.

Last 600 ft down slowed from 135 kts to 128 kts.

Last 54 seconds had pretty steady heading about 140 deg.

Starting the last two minutes, speed was about 150 kts for the first minute and a half and then decreased to 128 kts at the end.

During the last minute and forty five seconds descent started at -441 fpm and gradually increased to the -1161 fpm average, probably higher at impact.

It's a puzzler for sure.

Not a pilot but if it helps you guys to figure it out, I’ve driven through this city on our way up around Lake Superior and the whole area is built on a hill. The decline starts from about the edge of the green shaded area all the way to the water.

Possible.  I can't seem to find any info on the fog/icing situation over the lake that day.  Its not uncommon to see ice fog over the lake in the winter.

Betting engine failure/fire shortly after takeoff.  Flight track seems to suggest that.

Not sure what him being an engineer has to do with it, has absolutely zero bearing on his pilot abilities.  The news seems to think otherwise.

You can't tell engineers anything.

That is why the old school airplanes didn't even let them look out of the front.

man that really sucks....GA aircraft will let you get all crossed up in a hurry.

I always wondered why they just couldn't write some simple logic into the flight instruments....basically like having computer CFI in your ear.

The workload for single pilot GA is a lot for someone that doesn't fly every single day

A lot of GA (majority?) are still on steam gauges.

The cost to get something like that developed, certified, installed and maintained are crazy retarded expensive.  The vast majority of GA accidents are still VFR pilots flying into IMC or something along those lines.

Cessna 172 tend to be pretty dated airplanes and yet have an accident rate less than half of average.
