You openly admit you are too stoopid to calculate the air speed of a drone? Bret Cahill

You can always buy 400,000 drones. They already have 25 years worth of video of Afghan countryside, almost all of it is useless. Bret Cahill

Of course, if you are too stoopid to calculate the time it takes for radiation to be reflected back to a satellite then you aren't going to get good answers no matter what you try. Bret Cahill

By offering insultes instead of answers you show that you have run out of defenses for your hare-brained scheme. Work on your pitch some more--you're a long way from being ready for the venture capitalists.
