Two flights were achieved to demonstrate that multi-rotor aircraft can stay in the air carrying a payload for a long period of time. While 20 minute flights were considered long in 2014, these demonstration flights show that 1 hour flights can be the norm. Imagine the increase in commercial applications when it is common for ships to stay in the air for an hour or more carrying different payloads. It's just a matter of finding good rotors (Tiger), flight control electronics (3DR), batteries (Panasonic Li-Ion), ESCs, and removing unnecessary weight. Once industry realizes the importance of performance, we will also see a jump in rotor and ESC net-lift efficiency (lift after it gets itself off the ground first).
