Question Regarding 9/11 Planes...

Hi all,

I don't know anything about flying, and would like some answers from
anyone interested in responding.

For the record, I'm not here to debate this issue. I'm here for
opinions from people whom I'm assuming would know far better than I
what is a reasonable answer to this question:

It is claimed that the manouvers it took to fly the planes into the
two towers (leaving out the other planes) would've been exceptionally
difficult to perform. Some so-called professional pilots claim that
it would be very difficult to not only hit the two targets with that
degree of accuracy, but also that the turn in the air somehow elicited
some kind of excessive "G's" or whatnot (you'll have to fill in
whatever it is I heard elsewhere...I'm assuming it related to the
difficulty a human being would have to withstand the last turns at the
speeds that the plane was going at while maintaining control of the
craft, etc.).

Here's my thinking (again, as someone with zero experience)...if a
pilot can aim/land on a landing strip, why couldn't he/she aim/land in
the largest skyscrapers on the planet?

I don't see how it'd be that exceptionally difficult...but I'm very
open minded and would like to hear from those who'd know what they
think on this matter.

Thanks. I look forward to quality answers. And again, I just want an
unbiased opinion, I'm not here to argue politics or conspiracy
theories.
