- this answer to History of multiple-payload launches?
both describe a launch of GRAB1 that secretly contained a second payload ELINT. The second launch attempt was self-destructed because the first stage engines shut off 12 seconds early.
This apparently resulted in fragments falling on Cuba.
Question: What happened to the debris that the US dropped on Cuba? Was any recovered? Was it even noticed and/or reported in Cuba?
