Okay, fair enough. "Between" being a key point. There are plenty of 5 a.m. departures, and also some 1 a.m. departures. But the difference between 5 a.m. and 4:50 a.m. is huge, psychologically.
The CO flight you mentioned is basically a red-eye, but a domestic lower-48 flight leaving at 1:50 AM is indeed unusual. Any others?
