Flying only about 300 feet above the heads of two astonished humans (the couple had been taking a walk in the San Fernando Valley of Los Angeles County one night in 2009), the creature appeared to have a wingspan of 10-20 feet. Also astonishing was the faint glow that led one of the eyewitnesses to connect the creature with the ropen of Papua New Guinea.
But it was not the bright flash of the ropen that the Los Angeles creature displayed that night; the glow was faint enough to suggest a possible reflective quality on the wings. It was definitely unlike a bird.

Addendum:
To those who would dismiss accounts like this with “mistaken identification” I would reply with, “What was it?” If what was seen in Los Angeles County, California, in 2009, was not a giant glowing ropen, then what would appear like that and not be that?
Some ill-informed supporters of the concept of living pterosaurs have seen a video of a Frigate Bird and thought it was a ropen; that is unfortunate. Frigate birds are not ropens, and they appear very different from each other.
