[QUOTE="Bob Wright, post: 2743833, member: 104363"] Thermal imaging is not good for cold objects at high altitude. Then, radar doesn't reflect back very well on the balloon surfaces, just a small payload that might bounce back a weak signal. So, China is exploiting that. NORAD is scrambling for an answer, as they were primarily looking for bombers and warheads generating heat. Spy satellites should be able to optically pick these up (weather permitting), but no one is talking in the US government. [/QUOTE]
