Aviation Video: McDonnell Douglas DC-9 - Northwest Airlines27/11/2009You would have to have at least 500watt speakers on full volume to even come close to the noise level in the back of this 1968-made DC-9-41. Nonetheless one of the nicest flights I've been on. Gotta love the PW JTD engines. Includes engine start-up, powerback, takeoff, and landing clips.
