A lot of flying wing designs have stability problems. Easily solved if you put a modern flight computer in the control loop. Some of those old designs would be interesting with active stability control. I like the 162 just because it looks cool. The Ho 8n and the Lippisch LI P.13a were also reporte...

One of the daydreams I've had since is to see aging cured so I can spend a good 50 years doing nothing but building old school warbirds for stick & rudder addicts. Late Doras and C model 152's would be near the top of the todo list. Strip all armor and guns out and fix all the crappy slave labor co...

Eh, start at 1.3, ramp over 10 seconds to 2.5. Fuel is cheap.

I do not presume that limit is 1.3 g. I expect most people will tolerate 3g very well.

I can see advantages to burning one engine at min throttle throughout the flight until the 180 flip around. That would drastically reduce the Isp... Won't matter really, for one engine burning; one of so many will use little fuel even if on for a long period. The advantages of being under some thru...

As far as I am aware, Musk stated at the latest IAC conference the anticipated lift off G was 0.3 net, 1.3 thrust to weight ratio. He did not say it would keep that ratio throughout the boost. I can see advantages to burning one engine at min throttle throughout the flight until the 180 flip around.

Several distinctions between what is advantageous and required of an ICBM and and BFR doing Earthly P2P -- The ICBM must boost as quickly as possible to minimize it's detectable plume. This and the fact the BFR has many engines and they can be throttled (and not all burning continually) resolves the...

You Right for ... dams and geothermal But utilities operating as a monopoly should be forced to buy power from whatever source at their cost from their inhouse suppliers, less the cost of distributing it the average distance it is being distributed. Anything else is cronies being allowed to compete...

That ZeroHedge website hardly seems impartial. Not only is it not impartial, it is filled with the most unthinking set of conspiracy theory catastrophists this side of 4chan. These are the idiots who claimed un-broken, un-openable windows in the Mandalay Bay hotel were a 2nd shooter in Las Vegas--d...

I believe Antarctica is in it's "spring/summer" now, too.

" It is worth a mention that the US military entered WWII with some sectors of its tech in really backwards condition "

And some was superlative. The "any gun within range" artillery directing system was a terrible shock to the Germans, as was later the radar fuzed air-burst ammunition.

Real. Haven't you paid attention?

Sadly most people won't be convinced until you land a 747 in their front yard. Also sadly, that would be rather expensive. You can't really claim thrust that is on the edge of your equipment's ability to measure and call it a success. People should still be skeptical at this point. Whether optimist...
