The current "balloon" wars have been quite entertaining in a weird sort of way with a strange mix of espionage, propaganda and porky pies that are just enough to capture the public's imagination. Perhaps secretly we would like one of these unidentified flying objects (UFO) to be something a bit more mysterious than simply a common weather balloon. But we haven't quite yet reached the "little green men" stage.
The fact that they have started shooting down these mystery objects has made it a bit more exciting, just as long as ET doesn't get blown to pieces while having a quiet afternoon bike ride.
It's all a bit silly really as it is common knowledge all the "big" nations spy on one another. It at least serves as a reminder there are all sorts of objects whizzing around up there including things astronauts accidentally drop like toothbrushes, gloves, cameras and the odd stale pizza. There may even be a few thingamabobs and whatchamacallits.
