i dont believe in chem trails but why so many planes fly over the cities
 

common sense would forbid planes flying over the cities but they do in consistent basis

so is it somehow enforced for the planes to fly over the cities?

for the record i dont believe at all the chem trail nonsense but this kinds of back it up

imho if they wanted to spread population control poisons they would do it with car fuel as they did with lead but this got me curious, any reason for planes flying over cities?

Because cities have airports? :-P

Because they all carry nuclear bombs and the pilots are just waiting for the signal to go ahead and drop them, sheesh... you really really need to get your head checked out!

Look at where the airports were built in the first place, look at the area around them at the time they were built, and then look at how cities have grown between now and then. There's your answer.

Common sense would make people not buy into every single idiotic conspiracy-theory and actually do something useful with their blithering brains. Maybe I'm asking too much here, but seriously: Come the *censored* on.

Sheesh. And people wonder why I've never had much faith in the human race at all, and why I quite honestly think that humans are an evolutionary dead end. One would think that after 4 million years of evolution, we'd be further along. But no, we're not. Hell, I'd say that the chemtrail-idiots, and many of the other conspiracytheorists out there, are deadset proof that we're descendants of primates, and that some humans are closer to our ancestors than others.

Eh our species hasnt been around too long, a few million years is still new kid on the block in geologic time.

AS to the OP, well, I mean that's where people go, to cities. Very few flights going to the middle of nowhere.
And why would common sense dictate that they avoid overflying cities? What am I missing?

planes shouldnt fly over cities for the risk of them falling

is not this the reason for airports to be far from cities, maybe 30 km?

they want us to think of cheim trials so we dont think of lead in gasoline or fluoride in water

they dont put lead in gas anymore... :rolleyes:

It was used as a lubricant. If you buy an old car you have to add lead substitute... Anyway lead is not that bad and it tastes nice :-P

Lead is an abrasive. New car engines wear less than old "leaded" ones.

Proof?
Conventional aircraft engines burn 100 octane leaded gas. Their TBO after, 60 years is the same. Why? They burn the same leaded abrasive fuel.

:cool:

Airports were built outside cities for several reasons:
- they require a huge amount of land, hard to find in cities(and expensive)
- pollution and noise

Now, several decades later the airports are im the middle because the cities grew towards and around them.
The same is true for train stations btw.

Whats TBO?

So you are telling me Lead is abrasive to Steel? What? Please explain. :confused:
