Ok there are 3 woman behind true investigative journalism on Ufos - one you may heard is Linda Moulton-Howe from Earth files another is Paola Harris
As you probably know, Angelina broke the story to the world on the famous Stephenville Ufo sightings in Texas back in January, 2008. Then at the time she was a reporter for the Empire-Tribune who then eventually fired her, reportedly because they weren't too happy with her pursing the ufo topic further. It was no loss however - Angelina is now world famous for her outstanding and investigative jounalism which focuses on uncovering the Ufo topic.
From her bio : Angelia has appeared twice on Larry King Live and continues to do many interviews across the nation. Most recently she appeared on Discovery Channel Investigation X and worked closely with ABC producers on UFOs: Seeing is Believing, which aired on September 16, 2008, and resulted in a special thank you credit.
The Mutual UFO Network Texas branch recognized her in 2008 as the organization’s “lead investigative reporter.”
She has worked closely with Robert Powell, MUFON national research director, and Glen Schulze on the Stephenville radar report, which confirms an unknown object in the area on that now infamous night.
