Sounds like the detected craft were attempting to be stealthy and were caught out by military use of cutting edge technology as the "rules changed." That and we only hear about the well documented cases, where advanced sensors meet recording technology from multiple sources - military systems in other words. It would also be easier to find strange unauthorized stuff in the less populated and more heavily scrutinized areas - no fly zones monitored regularly by military staff for instance. Over land there is a lot of legitimate traffic to "hide" in.
