6,000 feet into flight maybe? Your original post says, "it was reported." I'd like to see an official report to find out whether that figure applies to altitude or distance.
Actually, what I heard on the radio newsbroadcast was that the passenger jet had reached 6,000 feet in altitude.
Whether that report was accurate or not - who can say?
Let me add, there are some things that were stated in that early morning newsbroadcast that stuck with me.
1. 6,000 feet in altitude
2. FBI says it may have been a flare or bottle rocket
3. It happened after departing LAX & while over water - the destination was somewhere in the eastern US
4. The pilot claimed he narrowly missed the missile
There may have been other details mentioned in the broadcast, but I dont recall them - such as the airline & destination.
