Compressor Stalls All the cool airplanes use turbofan engines. Sometimes, such as when shredding birds, airflow gets hosed and the combustion blasts out of both sides of the engine instead of just the back.  http://i.imgur.com/EyLNW.jpg Since this blows away the air being taken in by the engine, it goes out, and then immediately re-ignites, making a non-scary "chuf-chuf-chuf-chuf" noise if you're watching from a safe distance. https://www.youtube.com/watch?v=RPkZBR89y_M http://www.youtube.com/watch?v=RPkZBR89y_M

 duh. I even know what an F-16's HUD looks like, and that's clearly not it. One of the comments says it's a Hawk which makes much more sense.

I don't blame you for thinking it was an F-16 since the title says so, but that video has been around for years and this ONE GUY uploaded it with F-16 in the title one time and now it still gets shared as that. Post hot birdstrikes. https://www.youtube.com/watch?v=0zAZBfdvYwc

Here's a pretty cool AF training video about bird strikes: http://www.youtube.com/watch?v=Kiuut7ibmPg I was trying to find one I've seen before about a T-38 that goes off the end of the runway after aborting a takeoff due to engine failure (I can't remember whether or not the engine failure is due to a bird strike or something else) but I couldn't find it. Have this oldie but goodie instead: http://www.youtube.com/watch?v=B4VCV_z52GU Also, here's a cool picture of a new paint scheme the F-15 aggressors at Nellis have on a couple aircraft:

The Americans conducted years of expensive studies to determine the least-visible schemes for the majority of conditions under which their planes would be flying, increasing operational effectiveness by a small but definite margin. The Russians said "who cares about that poo poo, let's make it look loving cool". (fun fact: when they were developing the F-117, the Skunk Works did some studies to determine the least visible paint scheme for the high-altitude dusk raids that would be its main mission. The eventual conclusion was that the best color would be a dusty orangeish-pink. They painted it black because they thought no one would agree to fly a pink airplane.)

The same story has been applied to dozens of aircraft over the years, but in fact there were pink planes in the North Africa theater of WWII. Not popular, lots of jokes, but ultimately the guys flew what they were commanded to fly.

It's not *that* bad - breaking up a shape with camo is a good idea. The camo on the F-15 works well in the arctic, I'd bet. It just becomes a determent in the desert. Let's just make it look loving cool is Tigermeet.

Yeah, unless you're "forward deployed" to Europe or Korea and you're operating out of a HAS (and even not necessarily then), the only fighters that are all gonna be parked inside are the Raptors that have their individual cells.

That's probably because you're seeing the nozzles without the "turkey feather" coverings that a lot of aircraft use. IIRC, the covers were stripped from the F-15's due to a tendency to shed parts in flight from a vibration issue, so removing them cut down on maintenance costs/time, and it saved a bit of weight as well.

If you're looking at a plane's belly when you think you're looking at its back, everything you know about its likely motion vectors and maneuver limits is reversed. For instance you might see it making a lazy banked turn to the left, and you go into a lead pursuit...and then just as you realize you're looking at the bottom of the plane and it's flying inverted, it does a 7G reversal to the outside, requiring you to fly a negative-G maneuver that's way beyond your own limits to keep it in sight. It's not like it's an expensive modification, and anything that confuses your enemy for even a few seconds is a good thing.

Sagebrush posted:The Americans conducted years of expensive studies to determine the least-visible schemes for the majority of conditions under which their planes would be flying, increasing operational effectiveness by a small but definite margin. Actually, it was back in WWII when the Brits figured out that pink is a great color for low-vis in pretty much all circumstances, but like you said, pilots say "No way am I flying a plane painted pink." That light grey color is almost as effective, so everything gets it. Except the SF guys who love a black helicopter. Black shows up better even at night than grey does (the sky looks black because it's so dark, but there's generally enough scattered light that an object painted black will be darker than ambient and can be picked out easier, especially if it's moving). This changes at higher altitudes, so if the aircraft spends time up really high (SR-71, U-2, etc), it gets black. Lockheed knew all this, and so did the USAF. The F-117 wound up black rather than low-vis grey because it was felt that "If we paint these black, no mission planner who isn't certifiably insane would be tempted to use them in the daytime." After the whole Cold War thing wound down, they did paint an F-117 grey and evaluated it for daytime missions.

Loads of great F-5 aggressor photos. From a model airplane perspective, it was always a fun "What if?" idea, but it also reminds me of just how bad the enemy planes were in so many movies from the 1950s-1980s. Then for a short while you could buy MiGs or whatever, and now CGI means that we never have to be treated to a P-51 masquerading as a Me-109 (I'm looking at you, Aces: Iron Eagle III).

I could never enjoy Top Gun back when I was a little  about military jets because "those aren't MiG-28s, they're just F-5s painted black with stars on them! And the Russians don't paint their planes black, either, they're mostly just shiny metal! And the MiG designations are all odd-numbered so there would be no MiG-28 anyway!"I got over it, but it still takes me out of the movie to this day.

Sagebrush posted:Interesting how they've painted that one to give the wings an apparent planform like a MiG-21. I looked at those jets every day for two weeks and some change during Northern Edge last summer because they were parked on the ramp just outside our hangar (although really I saw everyone that was up here pretty frequently because I was more or less on the flightline for 12 hours straight those entire two weeks unless I was doing something at the bar), and it blew my mind when I first saw that in a picture because I hadn't noticed it before...only saw them from the bottom while they were flying, and I was never viewing from high enough to notice it while they were on the ground.

Colonial Air Force posted:Eh? From imdb: At the airport, the exterior shot of the plane flown to New York is shown as a Boeing 767-200, which, unlike the -400 series 767, lacks a middle door. When Kevin enters the plane, it is clearly a Boeing 757, evidenced by its single aisle and the door between first class and coach through which he entered, which even then magically becomes an Airbus A300 Cabin with the different overhead bin designs that did not exist on Boeing Aircraft at the time. American has also never flown 767s or A300s between Chicago and LaGuardia.
