“Threads like this one make me glad that evil people aren’t often very dedicated to lifetimes of study or hard work in any single pursuit of skills or invention.”
Some aren’t, but some are.
You will recall that the 911 planning team were engineers who calculated that if they crashed a fully fueled 757 into a Trade Tower it would collapse the tower as it did.
In the first Trade Tower bombing in 1993, these same engineers ALMOST succeeded in causing one tower to fall into the other and they did this be figuring exactly the location in the basement of the first tower and how much explosive would be needed to achieve that exactly the way that a lumberjack aims a tree to fall in a certain direction.
They also sent four highly educated, intelligent men to flying school to learn how to fly after they had seized the aircraft opportunistically with BOXCUTTERS.
I regard these dedicated Islamists to be fully capable of continuing to find new ways to crash airliners adding to:
1. shoe bomb
2. underwear bomb
3. toner cartridge bomb
etc...
We must not underestimate our enemy!
In brief, plain speech, it would be too difficult for anyone to hit a jet engine on a landing aircraft with a tiny, remote controlled helicopter. A tiny, remote controlled helicopter would be seen well in advance of doing any damage—not a situation that terrorists would like. Those toys have very limited time in the air (batteries) and are very easily affected by winds.
If a large jet aircraft were to hit such an object, it would probably land safely enough anyway. Many large aircraft that hit birds have landed intact except for engine/windscreen damage. Our enemies could much more easily design and build rockets to do that kind of damage to us, but they simply haven’t been so technologically motivated, yet. Even more easily than that, terrorists could buy antiaircraft weapons from the countries of our “trading partners” so preferred by big shot constituents over us: their own fellow Americans.
My general point is that there is no way to stop tens of millions of determined people creepy enough to be assassins because of their religion and culture from attacking us without destroying their will to fight on their own soil. Trying to catch them one or a few at a time, while they’re attacking or planning attacks, won’t work in the long run.
It’s also doubtful that we’ll turn ‘em all into homos and whores with cultural exchanges and monetary wealth (part of the problem). Some of the security methods used so far are causing a morale problem here, while the enemy is that-a-way (pointing to the Middle East and East)! We’ll have to fight a war and whip their behinds real good.
