I would say bullethead is the closest. A number of years ago, while working for unnamed national airline, I managed to get right up to AF1 while it was sitting on the tarmac (underneath the tail section). These small pods on all the struts have a flat face that is gold in colour and has a honeycomb pattern.
Of course none of the CIA boys would tell me, they probably had no idea anyway, they just told me in the politest way to get lost.
Anyway I must say it is the best maintained and cleanest aircraft I have ever seen.
