Narrative:

Climbing through FL240 at 320 KTS felt mod/severe airframe vibration from rear of aircraft. Aft flight attendants called us and said the rear of aircraft was vibrating very badly. Pilots could feel the vibration in the cockpit. Leveled at FL260 and started to slow to 270 KTS. As we slowed to 270 vibration lessened. Descended to lower altitude and slowed to 250 KTS and vibration stopped. Returned to our departure airport without incident. Filled out airframe vibration report and faxed it to maintenance.
