Reasons - Christopher

You're out in the cold

There's something behind you

You hearing the beat

My heart is inside you

You looking to hide

I'm looking to find you

Cause you can't run away from love

You're looking to break

Away from the monsters

A beautiful face and eyes like your mother

Got something to say

To say to your father

Cause I can't run away from love

I'll be the reason that you're loosing your daughter

She'll be the reason that you're gaining a son

She is an angel I thank God that I got her

And I promise I will love her more than the sun

You're out in the cold

There's something behind you

You're hearing the beat

My heart is inside you

You're looking to hide

制度问题，当年将飞机和发动机捆绑发展，飞机下马发动机也下马，到研制新飞机时以致没有合适的发动机，不得不进口受制于人。 先进的制造工艺、技术研究了不少，就是不能应用，最后还要进口，打压了自己的发展能力。 早点知道市场这个东西就不会是今天的样子，关键是航空工业的产权制度要改。

简单的讲：起步晚！

当年想走捷径，结果没走成，倒把自个的飞机工业给耽搁了。

苯么~

你说呢...

那就是因为有为数不少的像你这样的人，就是说像你这样心里老是想着：我们中国的飞机制造业落后于世界先进水平，所以飞机工程师恐怕也是这么想，这就造成了他们设计的即使有那不好的地方本可改正的非常好，就因为一想到不如先进水平，就使他们产生了惰性，对于我国飞机制造业的发展很不利。所以改掉你一禒海操剿鬲济叉汐常搂遇到问题就想到“我国不如某某”的想法吧！！！
