Re: Concord (sic) doesnt fly anymore.
At Flight Level 360 maybe aka 36000ft. Know many drones of the nonmilitary type that fly that high do you? (not sure many of those even can fly higher than 10,000ft).
FYI: I was replying to @RancidRodent, who started about cruising speed. I was not replying to @Simon Harris, who posted while I was typing my reply.
