If you look up the time you took the photo, and convert it to UTC, you can look at the playback on https://www.flightradar24.com/ . It's not the most intuitive interface though, and they have to have ADS-B transponders. There's also https://adsbexchange.com , I don't remember which is easier to use

PainterofCrap posted:As FuturePastNow beat me on, part of it was that most anything built in the last sixty years with sufficient thrust has a larger diameter and would drag down the runway, unless they installed shopping-cart wheels or something similarly Wile E. Coyote under the fan casings to prevent unplanned disassembly of the outer units. There are a small number of bizjet engines that mostly fit the bill.

hobbesmaster posted:I would assume those are all JASSMs or something so it’ll potentially be 1000miles away? That path leads to solutions that make more sense than using it as an AMRAAM-slinger. Some kind of LO cruise missile, or hypersonic missile, maybe. Something that makes this a better option than just hucking TLAMs from ships.

Apologies if this has been posted but a movie is in production about the air war in Korea and the first African American navy pilot. I read the book and enjoyed it They’ve been flying F4U’s out of my little hometown airport and are using flyable MiGs and Skyraiders too https://deadline.com/2021/02/devotion-jonathan-majors-joe-jonas-story-behind-movie-jesse-brown-1234684266/amp/

The biggest problem with Red Tails was that they sensationalized it too much. You don't have to make Mustangs into X-Wings. Not every pilot has to be the greatest pilot who ever lived, even though every Tuskegee airman had been excessively trained. The Tuskegee Airmen might be older and less CGI-ey but the cast is fuckin'  and it tells a way more comprehensive and cohesive story. It doesn't shy away from drama or obscure it behind  CGI.You also don't have a scene where a dude gets ventilated by 30mm Minengechoss that don't explode and lives long enough to smugly quip about killing the dude who killed him.

Paging Nebakenezzar... Humanitarian airship seeks world’s most powerful hydrogen fuel cell Apparently Sergey Brin's airship company wants someone to build them a 1.5 MW hydrogen fuel cell. Seems a bit ballsy to go "yes, our airship needs more hydrogen components, this has no historical echoes at all."

An airships is like the only vehicle large and slow enough that putting solar panels on it might make sense. The arithmetic may not work out on the weight, though.

If you don't have that glass layer on the outside I bet they're reasonably light.

vessbot posted:The Thunderbirds now are gonna get 2-seater F-16's with spines and conformal fuel tanks They've got a few 2-seaters. That's how you get all those celebrity videos. Technically those jets are supposed to be able to be combat ready in a few hours (minus paint). I guess reinstalling the gun is the biggest task. Hasn't been tested since 1988, though. Edit: That particular jet (a Block 15 F-16A) went on to Hill AFB, then back to the Thunderbirds, then on to train foreign pilots at Luke AFB until being retired and parked in AMARC since 1996.

Sagebrush posted:Instant reaction to the situation and nobody was even injured. That's about as good as it gets. I got to ride along an R44 pilot doing auto rotation practice once, I'mon mobile but that looks like an R44 or R22. As I understand it the beeping is the indicator to the pilot that the engine is loading the rotor instead of vice versa, and means that it's time to hit the button that decouples the rotor from the engine by loosening the idler for the belt that couples the engine to the rotor. The pilot could exaggerate a little, but with a recip engine I could totally believe that the time you have to hit that button before an engine failure steals all the energy from your rotors is .25 seconds. The autorotations we went through felt like a normal landing as opposed to the rough one in the video, but the guy I rode with also planned for them to happen.

Cojawfee posted:When the guy got out, it looked like the tail was gone I figured that happened when they hit the ground, since the rotor is sitting about 20 feet away from the rest of the helicopter. If the tail rotor failed in midair that seems like a much bigger deal than an engine failure. Engines are complicated things that do periodically break down, but the tail rotor linkage is just a mechanical shaft.
