There's a bunch of great stories about the development of the SR-71 in I think Ben Rich's book. Things like buying the titanium from the Soviet Union through several layers of shell companies. Or discovering that the chlorine-containing tool cleaners they were using reacted explosively with the titanium when you'd mill it. Or that if you drop a sheet of titanium the size of a garage door while you're craning it around the shop, it shatters.

Fucknag posted:Mikoyan-Gurevich: gently caress it, make it out of steel. Not just steel, but TIG-welded stainless steel. There was a real fear among the pilots before first flight that the aircraft would shatter on landing, as the welded joints did not have the same flexibility as a riveted/bonded joint. Plus, it isn't exactly a secret that making long, clean welds in confined spaces, such as in an aircraft fuselage, is by no means a guaranteed thing.

The MiG-25 is a pretty awesome plane, in a  kind of way. Heavy steel airframe fitted with fuckoff-huge engines that can zoom-climb up to 120,000 feet.

Yeaa...for reference, the CSXT team that was the first civilian rocket to break the edge of space like ten years ago only went to 116km. And if I remember that top gear episode correctly, even the U2 is only scraping 80k feet.

Bob A Feet posted:80k feet? How is the pilot not dead? MiG-25 and -31 pilots wear partial pressure suits, similar to what early U-2 pilots wore. And as a side note, a heavily modified Ye-155R (the designation given to prototype and pre-production MiG-25s) the Ye-266M, zoom-climbed to an altitude of 123,530 feet in 1977...a record for air-breathing aircraft that still stands today.

Apparently FAI witnessed some fairly impressive Mig-25 records, but not 100,000m. 100,000ft though, yes. They used the MIg-25 prototypes for the tests stripped back, rather than fully loaded beasts.wiki posted:On 25 July 1973, A. Fedotov reached 35,230m with 1,000 kg payload, and 36,240 m with no load (an absolute world record).[14] In the thin air, the engines flamed out and the aircraft coasted on in a ballistic trajectory by inertia alone. At the apex the speed had dropped to 75 km/h. The second one is on the FAI site. More interesting is that a Mig-21 reach 34 714 m. That's 113,891 ft. Truly the best plane

Altitutde records are fun:wiki posted:On June 21, 1972, Jean Boulet of France piloted an Aérospatiale Lama helicopter to an absolute altitude record of 12,442 metres (40,820 ft). At the extreme altitude the engine flamed out and the helicopter had to be (safely) landed via another record breaker — the longest successful autorotation in history. The helicopter had been stripped of all unnecessary equipment prior to the flight to minimize its weight and the pilot was breathing supplemental oxygen. Also please note that the altitude record for a self-launched (ie ground takeoff) rocket plane is something like 10,000m lower than the Mig-21. Just think of what could be achieved by launching a -21 from a bear!  (yeah, I know it don't work that way, but I can dream).

Mig-21. The AK-47 of planes. That is what went up there.  For whatever reason a -25 makes my brain go "sure, why not: It's all engine." But the old rear end Fishbed??

And considering the tiny fuel load, I wouldn't be surprised if it ran out of gas about the same time it hit that altitude. It's the better Russian F-104. Of course it has similar climb performance.

Sagebrush posted:Are there any major (let's say international) carriers operating right now that have never had a fatal accident? Never is a pretty strong word, and international is so vague. Bear in mind there are a huge number of airlines out there that simply haven't existed outside this incredibly safe modern era, and thus haven't (yet) had a fatality. Off the top of my head, an international airline that has never had a fatality? Emirates, for one.

US Air always seemed to have the slowest and most incompetent employees, but they make up for it by boarding earlier and taking more time to account. To give them credit, I had a flight from Columbus to DFW through ATL that was going to have a cancellation on the second leg. Their booking system automatically rerouted me through DTW.

Sagebrush posted:Are there any major (let's say international) carriers operating right now that have never had a fatal accident? Qantas haven't had a jet era crash or fatality. They famously spent 18 months and a ton of money repairing the QF32 airframe so they can still say they've never lost one. quote:On 22 June 2011 Qantas announced that it had agreed to compensation from Rolls-Royce of "95m Australian dollars" (£62 million/US$100 million).[50] VH-OQA was repaired at an estimated cost of A$139 million (~US$145m). The aircraft has four new engines, a repaired left wing (including 6 km of wiring replaced), and had extensive on-ground testing and two test flights. It returned to Australia on 22 April, and was scheduled to return to service on 28 April 2012.[51] The repairs added 94 kilograms (207 lb) to the weight of the aircraft.[52] Six of the of the twelve fatal crashes they've had were during WWII with two of those shot down by the Japanese. http://en.wikipedia.org/wiki/List_of_Qantas_fatal_accidents
