Don’t you just hate it when you get busted with speeding and receive a ticket? Wish you could just find a way to sneak past that pesky police radar? Well, chances are you won’t be able to…not unless you own your own stealth aircraft, that is.

Yes, the ever popular stealth aircraft. Most have admired them, some have even seen them, but few actually understand how they manage to get past the enemy radar undetected. Nowadays, it’s no big secret, but when this technology first came out, public misinformation was required to divert the public eye from the strange readings radars were getting.

The trick behind to so-called “invisibility formula” is to deflect or absorb most radar waves that the plane’s being bombarded with. This is why the shape of the plane is very important. Lots of sharp angles on the plane break up radar waves and deflect them in all directions, causing very little of them to bounce back to their point of origin. Although this is usually very effective on its own, the plane can sometimes be detected due to the faint readings it does send back. This was insufficient to make the plane fully invisible to radar though, so a way to deflect the last waves had to be found.

Since this was impossible without compromising lift, though, engineers came up with a different solution. Each stealth plane is coated with a special layer of paint, which actually absorbs radio waves. This, combined with the plane’s unusual shape, is enough to reduce its signature to the point where it becomes practically undetectable.

So, let’s recap: a coat of paint, a bit of reshaping and a little axel grease and you should be evading the police radar in no time, right? Well, not quite. Though this works very fine on aircraft, it hasn’t been reported to do as well on cars. Actually, the only effect it has had so far is increasing the amount you pay when you get a ticket, since evading police radar by this means is still illegal in most countries.
