Sorry, there aren't any pictures for obvious reasons. I saw a very interesting G-550 this week. From a distance it looked normal, upon closer inspection a more than normal amount of HD cameras probably allowing a complete sphere of vision around the airplane, some antennas I'm not familiar with and what appeared to be chaff dispensers installed in the tailcone piqued my interest. It had a foreign registration. I've been around long enough to know when to not ask questions, but I'd love to know what was up. Some people take security very seriously, I've seen armed guards behind ropes guarding aircraft before but this airplane had no security other than what the FBO provided. Just curious as to why?
