I've noticed that a lot of military jets often have an arrow decal with the wording "RESCUE" pointing to a rectangle of some sort. I tried looking around for information about it but I could not find anything. What is the purpose of that rectangle the arrow points to?
The other decals seem to be much clearer: e.g. the red triangles are usually ejection seat warning labels and jet intake danger labels.
My own guess is that it is a button/switch device to trigger explosive bolts on the canopy or another mechanism. If so, what does it look like and how does it function? A close-up and a detailed example would be useful.
