Great video.  I love how the radio communications are dubbed in.

Those compressor stalls are nasty.

Yeah, some wicked comp stalls. Pretty stable aircraft with losing an engine on climb out. You could see it pulling left when the TR was deployed on landing.

Good job Captain!

Did you hear on the audio that the airport ground crew found parts of the bird on the runway?  Coming soon to an inflight meal near you.  grin

I wonder what kind of bird.  Back in the late 1970s/early 1980s, my dad was in a plane that sucked a stinking GOOSE into the engine.  The engine did not make it, but the plane landed.

"I wonder what kind of bird."

An associated clip is from the evening news.

It said that not one, but two Herons had been sucked into the engine.

Probably that the engine casing could contain that mess.  But that's just my guess.
Or maybe they just wanted to see what would happen.

I liked they way they were congratulating that guy on blowing the turbine up. Get handshakes for blowing stuff up, that's my kind of JOB!!  grin

There was a ?C-135 that ingested geese on take-off from Elmendorf AFB in Alaska, lost one or more engines, and stalled trying to circle around for an emergency landing.  Killed something like 24 people as it was one of those with a bunch of electronic stuff and the operators in the cabin.

Sad

Modern jet engine cowlings are required to contain the parts should they decide to let go at high RPMs.  High-speed, sharp titanium parts do not play well with thin-walled aircraft fuselages and their contents.

Pretty much the scenario on United 232 in Sioux City, right Fly320's? Number 2 engine in the tail flung apart the turbine and severed the hydraulic lines.

Reinforced housings tend to help keep pointy, high velocity Ginsu-like objects from slicing important things.

Exactly.  The defect occured during the original manufacturing process years before the engine failure.  There is no reliable or cost-efficient way of catching that type of defect, so the manufacturers are required to make the cowlings contain the failure.

Tallpine, it was an E-3B (Rebuilt 707 w/low bypass turbofan engines) AWACS jet that crashed on takeoff from Elmendorf on September 23, 1995 after hitting a flock of geese, ingesting several into the #1 and #2 engines. 12 geese were also found dead at the end of the runway.  I lost several good friends in that crash, and the wing commander got fired for complacency with the BASH (Bird Aircraft Strike Hazard) program he had in effect.  The entire Air Force BASH program was subsequently revised and strengthened.

On approach to McClellan AFB in Sacramento several years ago, we flew through a flock of sparrows.  The TF-33s simply chowdered them and spit them out the exhaust and bypass stages. On walk-around afterwards, I pointed out to the crew chief the remains of one sparrow who had been buried beak-first into the leading edge of the right wing between the #3 and #4 engines.  We joked about the last thing that had gone through that bird's mind, but the damage to the airframe still required money and downtime.

When I was in Corrosion Control at Kincheloe AFB, Mi, in the 70's, we had a KC135 roll into the hangar with a bird strike to the right inboard wing.

There was a goose sized hole in the leading edge (inboard of # 3 engine) and goose feathers (and meat) spread throughout the entire leading edge of that wing.

Well, yeah, but seeing as it's "real meat", only in a first-class meal...

I love how that engine-cum-grenade test is categorized under "How-to/DIY".

Haven't you heard? No more knives allowed in the cabin, so everything has to be pre-sliced. The next phase of the research will be to find a way to direct the "product" into the galley.

Heh, cool. I like that clip of the blade being worked in the CNC machine. I have a good idea where it was taken because a big shop here in my area makes the blades for RR. Or used to anyways.

BTDT seen more than my fair of ingestations/strikes/busted windshields.  Hail damage, mid-air collisions, lightning strikes, ejections, deaths and carnage.
The last ingestion I witnessed as a Tower ATC was in Beaumont.....C550 sucked an egret in right in front of the tower.  I watched the whole thing unravel....

I've never run into that one ... perhaps it's a bit moot by that time Wink
