Other aspects of her research were known at least to Quinn before she died, but not her sources. As indicated by a 1992 letter to Quinn, she was adamant that Cabot had not vanished or been killed by Spaniards on the 1498 voyage, but had returned safely and died in England in 1500. Already she had published her belief that Bristol mariners had actually reached the New World more than two decades before Columbus planted the Spanish flag in the Caribbean. “I take the line that the Bristol discovery was pre-1470 but lost again until Cabot made landfall in 1497,” she reiterated in a 1988 letter to Quinn. While other scholars, including Quinn, had proposed that men of Bristol had reached the New World well before Christopher Columbus did, Ruddock would claim to have evidence for her early-voyage theory, from Italian and Spanish sources. She was also expected to shed more light on the long-debated connections between Cabot and his fellow Italian explorer for hire, Columbus.

If the B-2 was indeed downed, it is highly unlikely that the United States would acknowledge such an event, at least not for a very long time, if ever. This is especially true if the opposing side or neutral parties lack physical evidence, such as identifiable wreckage or sensitive components, as seen with the F-117. Without undeniable proof in the public domain, official denial remains a powerful and convenient tool. The other common response is no response at all, a calculated silence, or simply feigned ignorance. In such cases, the absence of acknowledgment serves as a strategic choice, allowing officials to avoid giving the story legitimacy or traction. This tactic, often employed in sensitive military or intelligence matters, leaves just enough ambiguity to stall public scrutiny while maintaining plausible deniability.

Acknowledging the loss of such an advanced and costly strategic asset could have significant military, political, and psychological repercussions, both domestically and internationally.
