Rebuild and tonal changes in 1984 as 3/29 Moller Op. R-151; the chapel was damaged beyond repair by Hurricane Katrina on August 29, 2005, and was eventually demolished; since the organ was installed directly in front of the large rear window, it probably also suffered catastrophic damage; the base suffered nearly $1 billion in damage from the hurricane.
Updated through online information from Greg Moore. -- I was an airman stationed at Keesler shortly after Hurricane Camille, in 1969. The roof of the chapel had been blown off, inundating the organ. The Air Force had planned to replace it with a Hammond, but two airmen who were organ buffs and the chaplain conspired to repair it by night, thus making it miraculously playable again. This was arduous work, since every felt was ruined and wood swelling brought about enormous problems with ciphers. I accompanied the chapel choir with music from Handel's Messiah at Christmas, the effective debut of the restored instrument, though I dared not touch the three or four notes that continued to stick (one was middle C). A remarkable act of generosity by those two airmen, whose names I do not recall. Reading about recent hurricanes, I remembered the organ and visited this site hoping to learn of its status today.
