Overflight only means out to 12nm offshore, then the flight is in international airspace. Argentina might control traffic, but their sovereignty doesn’t extend across the FIR. The Chilean flight transits the Argentine FIR and always has.

The C-5 with TF-39s were also dogs, but the wing was lighter loaded. I’ve seen 11,000’ plus all-engine take-off runs. Initial optimum on a warm Pacific out of Honolulu would be F240 or F250, the last couple thousand feet climbing at 500fpm.
