  1. I watched the Saturn moon shots on TV. I watched some shuttle launches. They were great. However, technology and design should be allowed to develop. Could you imagine if the planes of WW2 were forced to look like the planes of WW1?? Well, Artemis looks TOO MUCH like the bastard child of Saturn and Shuttle. I knew it borrowed concepts, but I was surprised to learn it borrowed actual parts. That's insane.

  2.  @johnrehwinkel7241  Physics has not changed. But, requirements do. The single use boosters of the Saturn V are great, but that is very wasteful. The new rocket should be reusable.

  3. In ancient times, Egypt was the wealthiest nation, and Carthage (Tunisia) was wealthy, too.

  4. $6.2 Billion?? Not hardly. $6.2 Billion is just for the ship. If the 70 airplanes are lost, at $60 million per plane, add another $4.2 Billion. Does anyone have any idea of how many rockets and what types they carry??? Sidewinders cost about $400K. If the ship has 1000 of them, then add another $0.4 B AIM 120's, AAMRAM, cost about $1M each. So, if 1000 of them, then another Billion. Billion here, a Billion there, and pretty soon, we are talking about real money.

  5. As a child, we had dime store balsa airplanes, that we flew by throwing them into the air. They consisted of 5 pieces--- the fuselage, the wing, the stabilizer, the tail, and a metal clip. The first four were simple...put them together, and you have your plane, or what looks like one. BUT, that metal clip was necessary. It was thick, and had weight. I now know it gave the plane a center of gravity where you put it. The plane behaved differently when placed in different places. As I recall, when placed forward, it would do great loops. Which was great. Placed more centrally, it would fly nice and level and go a long way --- boring, plus you had to go get it.

  6. AC transmits over distance better than DC. I believe that was the reason AC beat DC, which was backed by Edison.

  7. Most amazing invention?? Easy --- The Thermos bottle. It keeps hot things hot, and cold things cold...... How does it know??

  8. Best invention?? Easy --- The Brassiere. It led to the Bikini, and then to the thong bikini, while also giving us the push-up bra. Ancient man never went to the beach. Now, an entire beach culture rules us.

  9. The French could have had 10,000 tanks and they still would have lost. The Germans did NOT win because their tanks had superior armor or armament. The Germans won because --- 1) German tanks were organized in tank units, while British and French had them dispersed with the infantry 2) most of all, German tanks had radio, their attacks could be directed and coordinated. With no radios, allied tanks were useless in maneuver warfare, during the Battle for France.

  10. Some good facts, but off the mark. The blitzkrieg did not work in Russia due to Russia's size. It worked remarkably well, at first. Russian armies and land fell rapidly. But, the sheer depth of the battlefield meant that the blitzkrieg ran out of resources. Russia, like the other allies, eventually learned how to fight the blitzkrieg. 1. The allies also developed tank battalions, and put radios in their tanks. LIke Guderian, they, too, looked at Britain's Plan 1919 that was ignored by Britain during their tank design and war preparation. 2. The allies developed and used infantry anti-tank weapons that reduced the supremacy of tanks. So much so, that infantry had to be used with tanks to protect the tanks, thus reversing the doctrine of blitzkrieg. 3. The blitzkrieg was defeated at the Battle of Moscow. 4. The battle of Kursk was the final desperate attempt by Hitler to defeat Russia. It was defeated by Zhukov's defense in depth that prevented any blitzkrieg penetrations...plus, espionage supplied knowledge of the German battle plans helped.

  11. The reason the Air Force doesn't like the A-10 is because it has NOTHING to do with the Air Force's mission, which is more strategic in nature. The ONLY reason the Air Force has the A-10 is because the A-10 is a fixed wing aircraft, and the Air Force has responsibility for ALL fixed wing aircraft that supports the Army. Navy and Marines have their own planes, thank god. I wish Congress would fix this mistake made at the re-designation of the Air Force from the Army Air Corps.

  12. Leveled out??? Obviously, you are not looking at Indian, China, and the third world. Their CO2 emissions have skyrocketed. CO2 is now increasing at 3ppm PER YEAR (CO2.Earth) We will reach 500 ppm by 2050. Sea level rise will accelerate exponentially. We WILL see sea level rise of over 6 ft by 2100, IMO. By 2200, a sea level rise of 20 ft is possible, maybe probable. ALL coastal cities will be impacted -- some abandoned. Will the Earth be able still support 9 Billion people? If not tens of millions, maybe hundreds of millions will die. This is serious. VERY serious. But, hey, lets ignore it and have a good time. Right???

  13. The Chieftain has a great video where he explains how and why the Sherman was a great tank. 1. Shermans always traveled in platoons of 5 tanks, so they would naturally meet any German tank with 5 tanks. 2. Shermans were the most survivable tank in the war. He shows how easy they are to get out of. Much easier than British or German tanks. The stats show how FEW tankers were killed in the war. 3. He tells stories of how tankers would get out of a shot tank, get another, and get back into the fight. 4 He points out how the steeply sloped frontal armor gave it a high armor rating. Almost equal to a Tiger. Google him and check him out.

  14. Thanks for the info. I now know enough to build my own F-16 in my back yard.

  15. When we move to a renewable energy infrastructure, I think airplanes would be the only vehicles allowed to use fossil fuels. Coal & natural gas would be banned worldwide. Oil mainly used to power planes, and to supply the polymers for plastics, and fibers for clothing.

  16. Silly. That level of funding could replace all fossil fuel power plants in the world with renewable energy plants. Simultaneously, gasoline powered cars could be replaced with electric cars. Thus, the world's energy infrastructure could profoundly and permanently changed. I think this would be much better.

  17. Even today, flying a rocket like a plane sounds C R A Z Y ! ! ! And this was way back in the 50's, before computers.

  18. I think either the American attack sub or ballistic missile subs are way more expensive weapons than the F-35.

  19. A windshield cleaner?? Next, I suppose you will tell me that the A-10 has cup holders.

  20. What do you mean by "We don't have a captain steering the ship."?? Donald Trump is steering the ship. We can rely on him, the smartest man in the world. Behind him stands the Republican Party, the smartest party in the world. They have stopped climate change in its tracks in North Carolina by passing a law against it. What a brilliant simple solution!!! Republicans prove that passing laws is the way to solve all problems. PS. If you believe a word of that, then you are nuttier than Trump and the Republicans.

  22.  @seneca983  True. That piracy included slavery, and sex trafficking.

  23. A "carbon tax" is basically stupid because it assumes and encourages continued fossil fuel usage. We need to move off of fossil fuel almost completely. ALL power plants need to be replaced with renewable fuel energy plants. ALL cars & trucks need to be powered by electricity (or hydrogen)\ The sooner we do it, the better. That is our only hope.

  24. The A-10 MUST be retained. An exception must be made to let close air support fixed wing aircraft, like the A-10, to be operated by the Army. The "fixed wing" monopoly of the Air Force is wrong and silly. The specification of what the Air Force can fly, and what the Army can fly should be determined by FUNCTION, not configuration. The A-10 is much better at ground support and ground attack than the AH-64 helicopter. They perform a similar role, so Army should have authority over both.
