Regarding Garcia' remains, please read Los Halcones no se LLoran. All the details are there.
Clearly C-430 was flown by Diaz, as he was the only one that "landed" on the island and his was the only plane of the section that crashed there.
Regretfully, all books written so far, based on Argentine official (but incorrect) information have the serial numbers crossed.
