有个哥们儿说B-52可能就没进东海防空识别区
原文：
Actually it's possible the B-52s might not have breached the ADIZ at all. China's Ministry of Defense stated that the B-52s operated "about 200 kms east of Diaoyu Islands."
The Chinese ADIZ defines a point at 25.38N 125.00E. Google map shows the main Diaoyu Island has the coordinates of 25.75N 123.47E. At these latitudes, 1 longitude degree = 100 kms. So 200 kms east of 123.47 works out to 125.47. That means the B-52s were about 50 kms outside of the Chinese ADIZ.
看来美军的两架B－52到达钓鱼岛东200公里是事实，而钓鱼岛东200公里还在东海防空识别区之外。
