1 MILLION people aren't enough to see network effects?? Is 3M [1] closer to the magic number? I moved from Boston(4M) to Cleveland(1.7M) and although the lifestyle is different, there is still way more opportunities, culture, entertain

Hybrid Airships might not fair well on the particular log/log plot shown, but there are other figures of merit to be considered: Emissions, noise, necessary landing infrastructure, flight-time, fuel consumption vs. aircraft productivit

Many projects at NASA are just starting to ramp up open-source efforts, and it can be very challenging to publicly release aerospace toolsets. Give it some time to build up momentum.
