Haha joke's on you buddy, I grew up around aviation and know that log books and maps are what pilots must always have at all times in all situations otherwise they'll get popped by the FAA. Only recently have digital devices been allowed anywhere NEAR professional cockpits, having been slowly tested in civil aviation. Thus I concluded that an expanding sector with limited knowledge of traditional expectations - airspace 'n shit - might be marketable. Watching your comment turn grey and then to vapor is more "Classic HN" to me.
It's hard to see a market for something already built in for free (airspace restrictions) and anyone familiar with current drones would know this.
There would be value in being able to pull up my phone and find out "Yes, there are no arbitrary restrictions on flying right here".
All that without specifying whether or not you have knowledge in the space. You probably should have specified X and Y are already in the space rather than assuming that someone already has taken up space there.
