I have already concluded that the North Korean missile test was not a failure despite all the failure talk and now further information is coming out declaring the launch to be more successful then previously thought as well:

South Korean, U.S. and Japanese intelligence authorities are still analyzing North Korea’s April 5 rocket launch amid claims that the projectile flew farther than previously thought.

U.S. aviation and space science website Spaceflight Now on Sunday said the rocket temporarily left the atmosphere and flew up to 800 km further in the direction of Hawaii.

Based on analysis of radar data and data from the U.S. Air Force’s missile warning satellite, the website said the rocket actually flew 3,846 km, rather than the 3,058 km the U.S. and Japan had estimated.

It said U.S. and Japanese military authorities earlier believed that the projectile had a problem with its second-stage booster rocket, but now feel the second-stage rocket worked as programmed. But Spaceflight Now said the projectile failed to enter the normal orbit because the third-stage booster rocket did not separate properly.  [Chosun Ilbo]
