The Coast Guard doesn't operate refuelable helicopters OR tankers. And there aren't enough of the others in position to just ignore that it's a capability gap. Whether it's worth the investment to actually reduce/seal that gap or not I have no idea.

Well, I found their spiritual ancestor: I found out a most interesting thing about those lovely little Tecnam twins today: apparently, unlike most POHs that have a conversion factor to find grass runway performance from an established paved runway performance chart, the Tecnam is the opposite way around: its performance charts are based on grass runway takeoff and landing performance, and there's a conversion factor for paved runways. I guess they assumed no one would bother taking such a terrible plane to an airport with paved runways out of shame that they might be seen.

Offshore of CONUS (and territories) USCG's official position is to basically maintain aircraft capability to maintain enough transit and loiter time to put fixed wing aviation assets on target to drop life support resources to provide a sufficient time for an AMVER registered vessel to divert and extract. This covers basically all of the shipping lanes (plus a generous margin, hence the diversion of commercial shipping) between the US West Coast and Asia, including Polynesia, as well as the East Coast to Europe and the Caribbean.

Interesting. Do you know if they actually do that? Or is it like have of the military's positions where the answer is "We'll do X" when the resources available max out at about half of what's necessary?

An old link, but describes their offshore SAR mission pretty well. https://gcaptain.com/sailboat-dire-situation-hawaii-matson-containership-diverts-assist/ tl;dr: diverted a WC-130J on an active science mission to establish radio comms and position of a 43' sailboat that had been demasted by a hurricane. They then dispatched a USCG HC-130 to air drop a maritime dewatering pump and life raft + supplies, as well as another USCG HC-130 to plow holes in the sky until a commercial vessel could arrive on scene to rescue the crew. https://www.pacom.mil/Media/News/News-Article-View/Article/1724571/coast-guard-suspends-search-for-remaining-sincerity-ace-crewmember/ More recently, Sincerity Ace (650ft car carrier) reported a serious fire onboard as well as taking on water 1,800mi northwest of Oahu. 2 USCG WC-130's, 1 USN P-8, 5 commercial vessels were involved in the SAR op, 16/21 crew were rescued.

So is the Canadian Air & Space museum in Ottawa worth the trip? Aside from Pima I'm pretty close to tapping out the US with regards to aviation museums with one-of-a-kinds and must-see uniques.

I haven't been, but want to, as it contains the world's largest remaining chunk of Avro Arrow. I have been to the Warplane museum in Hamilton (min 5 hour drive from Ottawa, depending on traffic on the 401, which is not trivial) and they have one of the world's two flyable Lancasters. (For 3500 you can get a seat on a flight, if you got that kind of scratch.) I don't know if that makes it worth going to Hamilton but I'm glad I saw it. (The Bomber museum in Nanton, just south of Calgary, has a Lanc that can run and taxi but isn't airworthy yet. I think I remember hearing the Hamilton Lanc uses it as a strategic reserve of runnable Merlins.)

Well, because I'm a glutton for punishment and also because I kind of like to take a long drive from time to time, I'd be driving from DC to Ottawa - I figure I could come home the long way and spend a night in Toronto and check out both that museum and also the Canadian side of Niagara Falls on my way home.

If you've got the time and are going to come all this way, you could also head west from Ottawa to North Bay to check out the NORAD facility there, I'm pretty sure they do tours. Then head straight down to Hamilton and Niagara via the 407 toll highway (deal with the extoritonate toll price later) and avoid Toronto and most of the 401 entirely/to the extent possible. But if you do end up in the city, let me know and I might be able to meet up for a beer.

And while you're in Hamilton, you definitely need to get to the Canadian Warplane Heritage Museum, which is home to one of the two remaining airworthy Lancasters, among other things.

After the end of the war in Europe a pair of guys in a Jeep drove around visiting locations where RCAF bombers were being scrapped and cut out sections of skin with artwork. Also, they have Hitler's car. Just off the 401 between Ottawa and Toronto there's a decent museum on the base at Trenton. It was a work in progress when I was there, so I don't know exactly what it's like now, but it is the only place in North America that has a Handley Page Halifax. The Ottawa Aviation and Space Museum and Trenton both have a Canadair Argus which is a big impressive cold war beast that's worth seeing.

Their WA base is just down the road from my house, the kids (and I), love driving down to watch them takeoff/land. Crazy how filthy some of the PC-12s are when the come back from the bush, can't wait to see how the jets looks after a trip up north. The kids have been telling me all the about the "new doctor jets" for the past couple months, finally got to see one a couple weeks ago. Best part, they're way quieter than the PC-12, so it's greatly reduced the 4AM wakeup from the turboprop.  And yeah, I agree with the sentiment of others here, they're pretty awesome looking planes. Even more so with the fantastic RFDS paint job. Honestly, the RFDS is just pretty drat amazing in general.

joat mon posted:a fantastic US-1 documentary video Apparently noone clicked the link I posted to the US-2 doing the same thing, only even better. The thing has nearly 1000hp per engine more than the US-1: https://www.youtube.com/watch?v=_lY2GlzBAtM  The US-1/US-2 family is fascinating. They're capable of operating off high seas mostly because they use a fifth gas turbine engine to power a compressor for the (imagine for a moment the kind of compressor you could drive with a 1300hp turbine engine) boundary layer control system, which blows air over the ailerons, flaps, elevators, and rudder to enhance slow-speed lift and drastically improve low-speed control authority. This is something that the US repeatedly experimented with; Internally blown flaps (using compressor bleed air) were used on the F-104 and a few other fighters, and externally-blown flaps (using engine exhaust) are used on the C-17. No major US project that I can find ever used a dedicated compressed-air source like the US-1/2. Related content, the NASA C-8A QSRA aircraft making COD look easy. https://www.youtube.com/watch?v=k_eDutgh4IU Note the NASA/NAVY and USS Kitty Hawk markings. Someone got a little zealous.

Nebakenezzer posted:Thanks; as someone who is perhaps over-committed to diversity in aircraft this is my jam Essentially yes, instead of pushing the plane through the air to make lift, it’s using the turbine exhaust to move air over the wing. There’s a bit more to it than that with exhaust being hotter and therefore less dense, but that’s the gist.
