You 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 P&W JTD engines. Includes engine start-up, powerback, takeoff, and landing clips. Note I put more effort into capturing the engine sounds than making good quality clips...so dont mind the occasional flashes of the seat in front of me and my pants;)
