I’m listening to the Marshall Pruett series on John Paul Jr., who we recently lost at too young an age to Huntington’s, and now this. . .

No, that was a small and ultimately aborted attempt to graft some DoD missions onto an ultimately civilian project to get additional funding. The Space Shuttle has a rich and twisted development history that can’t be reduced into a single sentence. It is true, though, that design decisions to meet DoD needs that were Read more

Thank you for this much needed intervention. I hope he appreciates what a friend you are.

Brazing has been the primary way of making steel bike frames for the entire history of steel bike frames. Mostly lugged, but plenty of fillet brazing.

Read about ETOPS - TL;DR, the aircraft should be able to fly for a given period of time on one engine, and the aircraft must never be further away from an airport than the distance the airplane can fly in that time. It’s based on the likelihood of a double engine failure, and is based on airplane design, maintenance Read more

Look up something called “Balanced Field Length.” The tl;dr of it is that an airplane must have enough runway length to take off or stop after losing an engine at any point during the takeoff run.

They’re going for a more “Agile” approach to development than the “Waterfall” project management style traditionally used in aerospace development. Time will show which works better, but each launch costs a tiny fraction of what it does for the more traditional competitors to even put a rocket stage on a test stand Read more

Naah, just sharpen the leading edge to razor-sharpness. The bridge has gotta lose sometime!

Based on the following links, the individual blades for moderately-sized turbines are within the weight limits of a Sikorsky/Ericson S-64 Skycrane, but I’d imagine that the sensitivity to winds would make it impractical. Also, it gets expensive given the number of flights a full wind farm would require. Read more

JP Jr. was well respected in the racing community. JP Sr. was a scary, murderous rage monster who might have killed his own wife.

You are literally using the term “unstable” inaccurately. The 737 Max is not statically or dynamically unstable, by the definitions of those terms. The issue is that it has a different stick force/alpha profile from the prior variant when getting to stall-level alphas, that affected how pilots might react to it if Read more

I’m sorry I’m late to the party, but I might be able to describe the sales situation of this airplane. I’m surprised that it is priced as high as it is; I think the seller is counting on novelty value. It is beautifully appointed, although the flight instruments appear to be rather dated. Read more

I’ve always been a huge Will Power fan, maybe because my CART/ChampCar bias. I understand that he can be a bit of a case sometimes, but when he’s firing on all cylinders (which I wish was more often), there’s no one better.

That’s sort of what the F-16 does, with its reclined seat. For a fighter, though, the pilot still needs a range of vision, so I don’t know if you could create a practical design that goes much further.

That after the first two Nobel awards this year, in usually overwhelmingly historically male-dominated fields, the women lead the men, I see it as at least a small sign of hope that things are trending positively. This has made 2020 look a little less bleak to me.
