Other than the C-130 kill by FRS 1 were any re-supply flights cancelled or turned back due to CAP, NGS or bombing?
Hercules TC-63 was on a recon flight, and it was not a blockade runner, when shot down by Ward.
Besides that, most of the 33 resupply flights by C-130s had two or three attemps (and that means turning back to the mainland) before landing on the islands. Most flights were diverted due to frigates nearby, CAP or NGS. Same with the 16 resupply travels by F-28 and other Navy transport aircraft.
