No armor at the beginning i don t get it.

So much arguments... Makes me want to try settle it

Regarding body armor and why they start with not wearing any. Its not silly or stupid to believe that a highly advanced lifeforms invading our planet has weapons that renders our armor a liability especially when said armor is designed for another kind of damage all together. That said once you got more insight you can start to experiment and create new materials that protects better.

A reason why Airplanes fare much better could be attributed to pure distance since the alien plasma technology appears to lose allot of its effect in travel. Giving reinforced airframes might just keep the airplane together while its getting peppered to swizz cheese.

Being extremely hard to identify on radar (someone said 1% every minute) would make radar guidance in a moving scenario impossible. Especially for pre programmed software.

Regarding funding. At the start of the invasion there is probably allot of confusion about what is happening and not to mention people are desperate for solutions. The Xenonaut project is probably just one in a thousand different organizations that promises to deal with the situation. Also as time passes and the Xenonaut project shows itself to maybe be the only (however it might not be) one with any real effect it also becomes apperant that the alien invaders is not out to extinct humanity and scared people in power might turn their heads more and more at the idea of subjugating themselves by/or not giving resistance resulting in the wrath of the invaders.

Did I forget anything?

That also means that UFO have to be visible for radars otherwise ARH or SARH missiles just can't see it.

Both USA and USSR had no air-to-air anti-radiation missiles (ARMs) at that time (1979).

Actually you're wrong sort of. The Sparrow and other early radar missiles were in essence air-to-air anti-radiation missiles. They homed in on the radar waves bouncing off the target when it was locked up by the launching fighter. One of the main reasons they didn't work out so well was that obviously the firing plane had to maintain a radar lock on the target until the missile impacted. That obviously didn't lend itself to defensive manuevering or engaging multiple targets coming from different directions. And, of course, blasting your radar is a great way for the enemy to find you and alerts the target someone has radar lock on you. Modern radar guided missiles are much better because they are fire and forget. Edited September 17, 2013 by StellarRat
