I just have to wonder.... ?

Why don't we have one of those super fast jet ready to fly straight up to UFO to check what they are. Even though the chance of UFO appearing at the right time at the right place is very slim, it still better just video recording them and arguing with one other what they really are. Now i'm not saying this is the way to prove whether they're from somewhere else other than Earth, we just need to at least take a closed look at what they look like. Those photos or videos of UFO captured by people are too fuzzy. They don't have much details
