with obviously no MPA experience
Oh, it's such a difficult job that for years we sent our best people to that role (not!). How hard can it be to fly a large 4-engined jet around over the flat oggsplosh, throw a few sensors out and wait for them to report in, have a squint with the radar at a largely flat terrain for anything metal sticking out and look for large lumps of metal distorting the magnetic field. If it was such an involved job then you wouldn't find time to eat a crate of stew and a dozen dairy-cream sponges. Even the targets are slow at a maximum 40kts in most cases, nothing to hide behind apart from a large expanse of water horizontally or vertically; and those that want rescuing are polite enough to use flares or locator beacons to help our greatest aviators find them...
...have I got one yet?
