Mr. Funny Pants posted:Probably stupid question... Sagebrush posted:The tanks are usually installed close to the unladen center of gravity so that emptying them doesn't cause a shift in the overall loading moment. That's also one of the reasons fuel tanks are generally placed in the wings; that way fuel burn doesn't require continuous changes in trim. Watch videos of the DC-10 tanker. You can watch the nose coming down the entire length of the drop. You can see it with the 747 tanker as well, but it’s more obvious with the Douglas, imo.

President: "The fire is too far away and moving too fast! It's going to destroy the pyrovirus facility before any of our tankers can reach it!" Buck Splashwell, Concorde tanker pilot for hire: "Excuse me, Mr. President, but I think there's one thing you're forgetting..."

Mr. Funny Pants posted:Probably stupid question... Some of the longer airplanes are also set up so that the retardant tanks operate in a sequence with the most forward and aft tanks dumping as a pair, then the next most forward and aft ones, etc... which minimizes the CG shifting as they drop.

Wow, really curious about how that happened. Damage to #1 and the fuel leak visible might be damage sustained in the crash landing. Hot dogging with a close pass after breaking contact? Or just the mother of all overshoots trying to connect?

So, about where the tanker came to rest. Is the pavement grooved like that specifically to drain away fuel in a situation like this?

As noted that is just a plowed field, but you are onto something sort of. Many airports now have what is called EMAS, the engineered material arresting system, where the area beyond the end of the runway is made of concrete bricks designed to collapse and slow the plane down if it overruns.

It might just be an illusion, but the KC-130 looks like a hull loss to me. The wings look... A little droopier than they should be. Super happy everyone walked away though.

The governmental actors who pay attention to things like TACAMO missions do not need ADS-B to track the aircraft. 99.9% of the country doesn't know what an E-6B is, or what ADS-B is or how to receive those signals, so it's not intended to reassure civilians or whatever either. Also, they may not even have ADS-B on at all; the ADS-B Exchange website also reports aircraft locations by multilateral triangulation from mode S signals. As noted, those planes are up all the time; you can check the history of that particular tail number and see that it flies basically every day. That guy is reading way too much into the fact that he coincidentally saw one flying around off Washington at the moment he thinks Trump was officially diagnosed with COVID. It's just doomer conspiracy theory e: https://twitter.com/jimsciutto/status/1312027909390045184 of course, that's just what they want you to believe

If they started showing up on FlightAware or the like that would be interesting, but as folks have mentioned they’re not exactly stealth aircraft. I should have noticed it was an ADS-B exchange screenshot.

These planes do the same poo poo as everyone else in Class A airspace. Stop trying to find conspiracy bullshit. They squawk, they talk to ATC, they use callsigns anyone could recognize. They self-report on all the same poo poo as everyone else because it's required. Years ago the AWACS fleet almost got loving grounded because the RVSM upgrade was behind schedule. Same rules apply until airspace is shut the hell down 9/11 style.

That’s interesting.” Rich folk paying to not have details surfaced doesn’t really bother me but I do wish they’d show the military stuff or that ASSB-E would get a phone app or something.
