They can't of course detect whether an aircraft has drugs in it, but they can detect an unscheduled departure for example by IR imaging of airfields. | |

Presumably at least some of the wreckage floats for a brief period before sinking. 406 MHz ELTs transmit to satellites. Of course this is assuming that the tail of the plane doesn't go underwater immediately and continue to sink without a chance to transmit a clear signal first. | |

They are used against drug production, because coca plantations can be recognized by colour on a multi-spectral satellite image. Plus they can show paths even (to an extent) under tree cover, giving away locations of hidden facilities. They can show jungle airports as they are larger deforested patches, but they can't catch a suspicious plane. Radar or AWACS is needed for that. | |
