Obviously throat mics have come a long way since WW2, I've used a Racal RA-440 for film work, but I don't think you can get them any more. It worked pretty well, about as good as a normal boom mic. If you google around throat mics seem to be popular for the special forces crowd (or at least the wannabes? Don't think Seals buy stuff on eBay....), I would think that a modern throat mic should work well in an aircraft application if it can be adapted to the aircraft system.
