Someone can’t get a jet to do a fly over...With GPS of her last position, it should be fairly easy to see what’s going on...Or am I being unrealistic..
Your being unrealistic. (Sorry couldn’t resist). You actually need a high-endurance patrol craft of modest speed with a lot of trained eyes to be able to see anything on the surface. This is particularly true in heavy seas, fog, rain. Keep in mind that the boat may be down in the water or capsized.
