As part of my current job I have to read about 100 - 300 pages of technical material a day. I still read for pleasure, but less so when I cross that 300 page marker for a day. The worst was when I had to review ~ 10,000 pages of material fo

I collect watches and have a G-Shock for similar purposes. I don't need it for work because I'm in a pretty sedate environment, but I wear it to work sometimes because I just like it.

Not all clearances are created equal. I have heard of people being blindfolded at certain facilities, when they had vital work to do at a lower clearance level than would normally be allowed in that facility. Also there's nothing like

I have done this, and also had to return a smartwatch that someone (very thoughtfully) gifted me, because I can't wear it at work. And if I can't wear it at work, it's not really going to be of enough use to justify keeping.

Is DCS an effects based simulation, or does it actually attempt to physically model the performance of aircraft systems and threat systems?

F-19 Stealth Fighter was actually released the very day that the F-117 was announced to the public.

Another big highlight of the game was their (for the time and platform) pretty good RCS modeling of ownship against various threats. Your movements against the threat would change the threat's ability to see you. Opening weapons bay do

Been there, done that. My "panel member" for our telemetry and power design review was another electrical engineer who was senior to me. He was supposed to give me feedback leading up to the review, but he didn't. So when the

Fair point on signed vs encrypted, I was simply pointing out that the ordinary civilian GPS isn't all there is. And while that L1 GPS signal has had selective availability turned off, that can always be turned back on again. Plus, usin

GPS messages for civilian use are unencrypted. The US Military has access to another set of signals that ARE encrypted.

The airframe dictates the missions. The F-16's airframe is fine, but not stealthy. Stealth is crucial when it comes to taking out the tracking radars of most "strategic level" SAM systems (like the S-300 and S-400). The F-16,

Some more details to support your point: The test in question was not even an "F-16 vs F-35" exercise, it was a regression test of a new vehicle control law software with an F-16 being used as a visual reference for maneuvering ag

The major components returned to BAE in the US are probably related to the AN/ALQ-239 Electronic Warfare suite, which is made by BAE's US subsidiary. BAE UK does not directly control its US subsidiary. Just because Israel is allow

There is no such thing as an "export version" of the F-35. All F-35s have the same installed mission systems, the same avionics, and the same mission performance. This was one of the big goals of the program -- to give the US, all

You know what really boggles my mind? You are the only person so far who has had a sane reaction to this. All these other people saying "this sounds like fun" are making me cringe in revulsion.

I second this recommendation. This is an excellent book about the Saturn V system. I also highly recommend Jonathan H. Ward's two excellent books, "Rocket Ranch: The Nuts and Bolts of the Apollo Moon Program at Kennedy Space Cente

I took several courses in computational fluid dynamics while in graduate school from a professor who had begun his academic career in the late 50s. He had worked for the Army on ICBM re-entry vehicle dynamics, worked for JPL planning space

How is an emoji a whole new way to communicate? EDIT: I meant this as a genuine question, not as a "how could you possibly think this" response.

The concept is simple to you because cruise control is such a common feature in cars that you only notice its absence. You understand exactly what a cruise control does and how to control one. Now consider being in the 1950s -- probably you

Yup, I have heard many a fighter pilot say things like "Over-Cranial Projector" instead of "Overhead Projector".

The F-15 is indeed a proven design, but against modern integrated air defense systems it is going to have a really, really hard time without extensive support from other platforms (EA-18G for protective jamming as just one example). And eve
