Flock that big I’m surprised they didn’t see any of it coming beforehand and delayed/canceled the takeoff, not uncommon to have to do that at SMF and OAK. I’m not familiar with the layout and visibility at SDF though

Looks like a starling murmuration. They move around surprisingly fast.

Am a birder and I agree. Last year I was waiting to board a flight at FLL and was staring out the windows overlooking the airfield. A murmuration of starlings materialized and grew to roughly 500,000 birds within minutes. (I know how to count large numbers of birds).   It was extraordinary. I'd always wanted to see a murmuration in person. But it was definitely a solid example of "be careful what you wish for."

LOL that would make it at least twice as hard! I'm trying to imagine counting the wings of hundreds of thousands or millions of birds and my brain just broke.

Ehh, you won’t be able to see a flock of small birds like that before it’s too late. My last bird strike was into a flock like this on approach, and I didn’t see them until about 2 seconds before they hit us.

It must have reeked inside the jet. Ingesting all those birds causes a stench in the air taken from the engines to run the air conditioning packs. And, this is the least of the problems from the bird strikes.

Flight_to_nowhere_26@reddit

It is disgusting. We hit seagulls going into MYR once and the smell was awful. Like fried chicken and burned hair. I was on the same AC a month or so later and it still reeked. Pax would ask when we were serving the meal because it smelled so delicious onboard. We didn’t serve hot meals. It was fun to watch their face when I told them what they were actually smelling.

The air conditioning packs use air from the engines that gets transferred to the cabin? I kinda always figured there would be some kind of heat exchanger, but then again I don't know jack shit about how AC on a plane works.
View on Reddit #72115593

gbettencourt@reddit

It’s not just about heat exchange, you need compressed air to pressurize the cabin. Conveniently jet engines are really good at that. So some air is bleed off the compressor side and fed directly into the cabin (after some conditioning)
View on Reddit #72115781

spacehog1985@reddit

Ok, that makes perfect sense now. Also, eww that had to smell like hell.
View on Reddit #72116775

AWildDragon@reddit

The 787 is a rare exception to not use bleed air.  I suspect we will see more jets that don’t as the effects of volatiles from the jet fuel getting into the cabin get better understood. 
View on Reddit #72118732

avgprius@reddit

So where do they pull in more air from?
View on Reddit #72147920

AWildDragon@reddit

Ram air ducts under the plane around the middle. 
View on Reddit #72162551

avgprius@reddit

So they just push air in vs pumping air?
View on Reddit #72177568

AWildDragon@reddit

For the initial stage it’s gets pushed in via the ram intake. After that it’s just a classic electrically powered ac system 
View on Reddit #72230634

avgprius@reddit

Ah
View on Reddit #72234520

Tauge@reddit

I believe the 787 system also brings about weight and maintenance reductions because it eliminates many pneumatic components that are required on a traditional bleed air system.
View on Reddit #72133636

Stoney3K@reddit

*Especially* with the entire LRD fiasco which causes the cabin to fill with smoke when one of the load reduction devices was tripped.
View on Reddit #72130595

Condurum@reddit

The compressor is upstream of the fuel, but oil vapors from the bearings I can see making its way into the bleed air.
View on Reddit #72129283

Stoney3K@reddit

Only in certain engine types - a lot of aircraft have heat exchangers and air cycle machines (which are basically turbocompressors driven off the engine bleed air) to compress the outside air for cabin pressurization. Usually you want to avoid pressurizing using engine bleed air directly because it contains fuel and oil fumes.
View on Reddit #72121787

Lwashburn66@reddit

Mans not wrong. This is why the early 707s used turbo compressors in some of the pylons, and the DC8 had those distinctive nostrils in the nose. It's kind of outdated, but this was true for a long time (the part about engine bleeds air being contaminated)
View on Reddit #72130458

Stoney3K@reddit

Also the 787 uses electric compressors to supply the cabin with outside air instead of engine bleed air since it has no bleed air system to begin with.
View on Reddit #72130540

biggsteve81@reddit

Air cycle machines are designed to cool and dehumidify bleed air before it is sent to the cabin. They don't mix in any ambient outside air, that is just used for cooling the heat exchanger.
View on Reddit #72130418

responded@reddit

This YouTube Short illustrates it, seems like it's just a pipe off of the compressor stage, before the combustion chamber: https://youtube.com/shorts/-xzWHHsttsU

Ok_Entertainer4453@reddit

Airport biologist here. Modern high-bypass turbofans can usually survive smaller birds going right through the motor with minimal issues. Large numbers of them may cause more problems. They'll definitely be doing borescope inspections and pulling feathers out of the blades for a while. At least at my airport, all of our ingestions of smaller birds have gone right through with no damage done. Still ruins everybody's day though.

My first thought while watching this video was the crash of ab Air Force Boeing E-3 Sentry that killed all 24 crew members. From Wikipedia: As the E-3 rotated, it ingested multiple birds(Canadian geese) into its number 1 and 2 engines. The crew started to dump fuel and initiated a turn to the left to return to the airfield, but with a full fuel load and having lost two engines on the same wing, it was unable to maintain altitude. After the aircraft reached 250 feet it descended and crashed into a hilly, wooded area, and exploded.
