Help me remember the name?

I watched a minute of a new anime I have never seen before some days ago, but now I have forgotten what it was called and can't find it again.
You see some planes with some guy saying something in the radio maybe, and another voice repeats it. That happens 3 times.
Then you look inside a house where a brother and sister is talking. they see something coming toward their window really fast. Then some girl is inside the room on her knees talking.

Can someone help me what with what that anime is called?
