The aerial view of 669HA getting scrapped shows a large canister type object on the ground close to where the engines would be located.
That same canister can be seen in the OP ground level "decompression" photo, on the right side.
The OP photo shows an aircraft in the beginning stages of getting shredded, nothing more.
This airplane was flown to the boneyard fully intact and subsequently scrapped. There was no decompression event on it.
