The window for shooting down the satellite opens in the next three or four days and remains open for as many as seven or eight days, said Marine Gen.
I wonder what "the window" refers to. At first, I thought "the window" might be a gun battery that has something like a shutter.
Then I looked it up in (on?)Dictioary. com.
6. a period of time regarded as highly favorable for initiating or completing something: Investors have a window of perhaps six months before interest rates rise.
It seems that the definition #6 is an reasonable explanation for the "window".
If so, what does "open(s)" mean?
I take it as:
"Shooting down is prepared in the next three or four days and it will take seven or eight days."
Is this very far from the original?
Any comments (except a political talk) would be much appreciated.
