The Hawker 125-700 that crashed last year in Akron took the lives of nine people. Since the November tragedy, the NTSB has been working on a report on the details.

That report has been released, though it doesn't offer what they believe caused the crash exactly, but it does contain some new details. What we do know is that the pilots disagreed over their rate of descent in the final moments before the crash.

Also notable is that the pilot allowed his co-pilot to fly with passengers aboard. Why's that notable? Normally that situation only occurs when no one else is aboard.

Based on eyewitness reports, the plane clipped electrical wires before hurdling into apartment buildings on Mogodore Road in Akron on November 10. No one was inside the apartment complex at the time of the crash, but everyone onboard was killed. The passengers, Diana Suriel, Thomas Virgin, Nick Weaver, Jared Weiner, Diane Smoot, Ori Rom and Gary Shapiro were employees of Pibb Enterprises in Boca Raton, Florida, a real estate company. The pilots, Oscar Chavez and Renato Marchese were also based in Florida.

Here is a transcript of the conversation between the pilots during their descent (HOT 1 is the pilot, HOT 2 is the co-pilot):
