Mr. Paiva appeared on camera to discuss his analysis of unidentified lights thought by some to be evidence of chemiluminescence in giant flying creatures known as Ropens or pterosaurs.
Chemoluminescence is the emission of light with limited emission of heat (luminescence), as the result of a chemical reaction. Mr. Paiva analyzed film from several sightings featuring maneuvering lights from an unknown source.
According to his site where the results and explanations for the results of his analysis is posted:
“Image processing for this section is implemented by (Clifford Paiva); the hardware and software computer integration being provided by (his) son, Mr. Alexander M. Paiva specifically for The History Channel Monsterquest Flying Monsters program.
Hydrodynamics of lift forces, coefficients of lift as a function of pterosaur wing area, and overall dive velocity profiles were included in the follow-up technical report to be released August 2009.”
