Take Pictures Too
It’s good for folks to get up in planes and try to spot Jim, his boat, or other clues. And it’s good to have satellite data. I suggest we combine the ideas and try to have a second spotter in the planes who is taking (hi-res) pictures so that eyes at home can comb through them looking for things that might not be evident from a moving platform. The pictures can be posted somewhere for volunteers to examine. When the pictures are of coastline or slightly inland, it’s probably ok for the spotter to merely note rough position. If something is spotted, I’m sure we can figure out where it is by comparing to clear satellite images.
