Why cant you all accept the fact that it is going to happen someday.
Because it's not.
Read the thread. Lots of good reasons listed.
If you sit in a cubicle for a living, this may seem like an achievable goal. But if you've actually navigated an aircraft in the real world for a considerable distance, you understand the vagaries and the risks, the unexpected scenarios that could never ever be programmed or handled via datalink. Combined with the incredible level of safety that would have to be achieved to make such an idea feasible to the travelling public, the insurers and the regulators.
Not to mention the incredible cooperation that would have to exist among nations to allow such activity in their airspace. I've flown in areas of the globe where they're just now getting the HF procedures down. And they're going to allow unmanned aircaft to shoot approaches into their major cities? Why - because YOU say they're safe?
