Pterosaur Interpretation of Cheesman Sightings
From Cheesman's book "The Two Roads of Papua"
"While at Mondo I witnessed a most curious phenomenon . . . [on a clear still evening with no nearby storms] suddenly I saw a flash of light somewhere below the horizon. It was rather a slow flash . . . perhaps four seconds . . . in a moment it came again . . . about four or five seconds, but that flash had been a little distance away from the first. Flashes continued at intervals. . . . a most intriguing mystery; because by no possibility could there be human beings out there using flash-lamps at intervals. . . . The flashes did not appear at regular intervals, sometimes there was a pause so long that I thought they must have stopped. At one spot three flashes followed one another rather quickly."

Evelyn Cheesman surely never dreamed that the strange lights were the bioluminescent glow of modern living pterosaurs.
The biologist-explorer Evelyn Cheesman was intrigued by the slow flashes of light that she witnessed deep in the interior of the mainland of New Guinea.
Early 20th Century Sightings by Cheesman
Lucy Evelyn Cheesman wrote "The Two Roads of Papua" (Published by Jarrolds, Limited, in 1935), in which she described the strange
lights that defied any explanation related to human origin. She saw that it would be unreasonable to suppose that the natives could
have produced the lights. Eventually she gave up on any clear explanation for them.

Cheesman noted that the lights appeared "more or less in a straight line horizontally." At first, she compared the first flash to a human-operated flashlight. She eventually became convinced that thirty natives would be required along a line 2-3 miles long: impossible.

According to some natives of Umboi Island, the ropen flash lasts about five seconds
