Pentagon says North Korean missile launch was longest in regime's history

The Pentagon says North Korea's latest intercontinental ballistic missile test on Friday was the longest test in their history.

Officials say the missile flew for about 45 minutes -- five minutes longer than their July 4 missile.

They say it flew 2,300 miles into space.

Sen. Dianne Feinstein told CBS News that the latest analysis of the missile would enable it to go 6,000 miles and even hit as far east as Chicago.

In response to the North Korean launch, the U.S. and South Korea launched a series or short range missiles on the same day.
