Why is everyone so quick to say that when allowed, commercial drone flight should be daytime only? Where is the logic to support that? In manned aircraft, night landings get special attention in training and in currency requirements because landing a manned aircraft at night has some physiological challenges that do require different training. But that is all from inside the cockpit. When landing at night it is particularly difficult to determine the height above the runway and can cause an early flare and subsequent hard landing. But, if you can see your Phantom's lights well enough to keep it in sight and away from obstacles, why should there be any restrictions on night flight?
