Newly released Pentagon documents show that Air Force officers debated briefly about burial at sea before concluding that 1,321 unidentifiable fragments of remains from the 9/11 attack on the Pentagon should be treated as medical waste and incinerated.

A string of emails running from Aug. 5-7, 2002, reveal that an unidentified Air Force colonel suggested scattering the already cremated remains at sea. A second official -- a civilian and -- said it may be appropriate to also have witnesses and a chaplain present.

Their arguments that the 9/11 remains weren't just normal waste were rejected by others who concluded the material was medical waste and should not be treated like human remains.

The emails were among nearly 2,000 pages of documents released by the Pentagon on Friday detailing operations at the mortuary at Dover Air Force Base in Delaware, investigations into problems and mishandling of war dead and other remains there and records about the disposal of body fragments.
