GULF.

Over the following weeks and months, Walters supplied dozens of additional photographs to the Gulf Breeze Sentinel newspaper and to MUFON. Many of the images were of striking clarity and showed an apparent craft with a "ring" of windows above and below.

MUFON's principal investigator on the case, Dr. Bruce Maccabee, undertook a multi-year analysis of the photographs and Walters's accounts. Maccabee published Ed and Frances Walters's book The Gulf Breeze Sightings (1990) and his own analytical book UFOs Are Real, Here's the Proof (1997), arguing that the photographs were consistent with a real, distant object. Multiple independent witnesses in the Gulf Breeze area also reported sightings during the active period.

In 1990, after the Walters family had moved out of their Gulf Breeze home, the new owner reportedly found a small model in the attic. Photographs of the model bore strong visual similarity to the alleged craft in Walters's photographs. Walters denied that he had built or hidden the model and suggested that it had been planted to discredit him. Investigators including Rex and Carol Salisberry of MUFON Florida resigned from MUFON over disagreements about the case, arguing that the model and other inconsistencies indicated a hoax.

The Gulf Breeze case remains contested in UFO research. Mainstream skeptical analyses generally treat the photographs as a hoax based on the model evidence, the photographic technique apparent in some images (such as a possible double-exposure), and Walters's behaviour during the case. Pro-case analysts including Maccabee continue to argue that core photographs withstand technical analysis. The case is included here as one of the most influential photographic UFO cases of the late 20th century, with the explicit caveat that its evidentiary status is seriously contested.
