@FlightQ Comments following the latest challenge- When trying to choose a flight with a layover, you cannot know if it's with the same airline or 2 airlines until after selection? And layover duration only counts when they're not within the selected flight? Else a very fun game!

@JonathanLandolt The logic should be physically touching so Malaysia and Singapore should be counted. I’ll fix that as well. Feel free to reach out whenever you spot any bugs there are places in the system so it’s not unheard of for mistakes!

@FlightQ Is it new that you can no longer re-submit a Layover attempt? The submit button seems to say no, the message below seems to say it should remain possible.

@FlightQ One last question... is it normal for countries like the UK and France, or Singapore and Malaysia, to not be considered as bordering countries?

@FlightQ Exactly!

@FlightQ Aw, darn. Any way you can add a "save" feature? It was nice to be able to submit a "good enough" attempt to avoid having to memorise it and then reattempt new routes.

@JonathanLandolt Good spot. Yes only one submission. I’ll change that text.

@Spookyload @ThunderCrate6 @eagledynamics If you look at the other images that were published, I believe the probe is angled to the right of the aircraft. Similar to what is done on other aircraft (like the Rafale), to expressly avoid it being in the middle of the hud. If not, I agree it would be annoying.

@JonathanLandolt @ThunderCrate6 @eagledynamics You probably won’t like seeing the probe smack dab in the middle of your hud

First I was like, “YESSSSSS!” Then I was like, “Wait, now I gotta learn how to do that too…”

A reminder to people who don't think "small" tsunamis are a big deal: even a 30 centimeter Tsunami can easily knock down a person. If you are in an area with a tsunami warning, you should take it very seriously. x.com/Prem_singh099/…

@justinsoliz @realmikeglynn Of course, there was also ETOPS which didnt exist early on. Nowadays, with modern engines, the cost of an additional engine outweighs the efficiency loss in terms of overall operating cost. Hence why most are 2 engine aircraft (see A340 vs A330 as an example).

@justinsoliz @realmikeglynn A lot of nuances but, 1 key item is you need to be resilient to 1 engine failing i.e. on a 2 engine aircraft, maintain flight on 1. if flight = 100%, you need 200% total thrust. With 3 engines, flight on 2 (150% total thrust). Means you can improve efficiency in the design.

I'll start by saying that investigations take months if not years to establish causal factors. I'm not claiming I know what happened - that's for NTSB to solve. That said, there's small detail, captured in photo #6 of the report that gives possible insight into UPS 2976. ⬇️ The preliminary report confirms what many of us suspected based on the debris field. Namely, that the engine #1 pylon failed and that the nacelle and debris from it flew upwards and over the fuselage of the aircraft, coming to rest on the starboard side of the jet's path of flight and the western side of rwy 17R, opposite the side of the engine's location. As some have pointed out, the loss of one engine would not necessary cause the loss of the aircraft, as MD-11 like other trijets is engineered to suffer an engine failure and maintain appropriate climb performance. That being said, if debris or foreign objects from an uncontained engine failure or separation of the motor entered any of the other engines, it would be quite possible for that engine to suffer a compressor stall at the least or failure from foreign object debris (FOD) injection. The sixth screen capture shown in the NTSB report shows what appears to be a flame near the vertical stabilizer, separate and distinct from the flames emanating from the port wing where the #1 engine separated. It's possible, that what the camera captured is flames of a compressor stall. I've circled it in red in the photo here. If FOD ingestion of the #2 motor caused loss of power, then none of the forecasted climb performance could be in any way met. This is just pointing out a detail I noticed while reading the report - it is in no ways claiming I know what occurred. The pros will determine those details in due course. The final NTSB report will tell the story of what happened following the separation of the #1 motor. They'll give us the answer to what really happened. Until then, respect for the brave UPS crew who fought this and flew it to the end. Pray for them, the victims on the ground, and all their families and coworkers. RIP.

@smartereveryday Webplotdigitizer works quite well. V4 still works without an account

(Nerd Challenge?) While working on my school stuff, from time to time I stumble upon the need to pull actual data off graph images. Does anyone know of an app or program where I could drag images like this into it and it would give me a CSV(s) of the data? (Random Examples)

@TheBrianMcManus @PhazzeeYeehaw Great video as always. Fyi, you accidentally put helium instead of hydrogen in the long march description drawings.

@PhazzeeYeehaw Some last minute edits to sponsor read, but should be up tomorrow morning

New video is on Nebula now

@wendoverpro Tag: New York edition?

Realizing the best way to make trains happen is to give you freaks an ultimatum: unless America gets more trains we’re gonna run out of filming locations and Jet Lag will end. Now get after it.

@soren_iverson Or the opposite... "Janet has been hovering over the mute coworker button. Maybe you should stop talking"

Google Meet feature to notify you when someone's been hovering over the unmute button and has something to say.

@jonostrower Someone once said, "There's always an aviation angle."

Apple on its livestream just touted its use of increasing product shipment by ship rather than airplane, "which reduces emissions by 95%."

@RenatoChem @Aviation_Intel My initial guess by rebuilding the aircraft and based on available imagery was ~135ft wingspan. Seems like those images were accurate enough for the front and top of the aircraft. The trailing edge kink needs to be moved inward based on the flap position. twitter.com/JonathanLandol…

@Aviation_Intel Nice! Any estimates on dimensions?

B-21 Raider Seen Like Never Before In New Images thedrive.com/the-war-zone/b…

@imjabbers Never knew these existed, but this seems to provide an interesting overview. ww2data.blogspot.com/2017/01/britis…

Never seen or heard about this, anyone got more info on how they are used? Or even a correction as to what this actually is?

@AGeeknologist They quietly promoted their hydrogen aircraft concepts at Aero 5 years ago, and then went very quiet... Interesting to see them reappear!

I was totally unaware of Apus, a small hydrogen aviation startup, at Strausberg, near Berlin. They seem to intend to develop a small hydrogen aircraft and have a first flight in 2024...
