Donald Trump embarrassed himself by not understanding fiber optic cables during a public briefing at the White House on Tuesday morning. The current U.S. president, now serving his second term, criticized Transportation Secretary Pete Buttigieg for what he inaccurately described as “putting copper into glass.” The comment came while he addressed the FAA’s ongoing modernization of its communication systems—a critical part of the NextGen infrastructure overhaul.
Trump’s misunderstanding of fiber optic cables quickly drew widespread attention, as experts clarified that the FAA’s project involves replacing outdated copper wiring with high-speed fiber networks, not blending materials. Engineers and aviation officials emphasized that the move improves signal clarity, enhances air traffic safety, and strengthens data flow between control towers. The president’s remarks, described by one official as “technically incoherent,” reignited questions about his familiarity with the science behind major federal upgrades.
Trump’s Misstep Draws Expert Corrections and Public Criticism
Donald Trump embarrassed himself by not understanding fiber optic cables when he panned Pete Buttigieg for upgrading the FAA’s copper wiring with converters, insisting—incorrectly—that “you can’t just put copper into glass.” His statement, made during an aviation technology roundtable, was met with confusion from attending engineers and policy advisors. The president framed the upgrade as “a wasteful experiment,” misrepresenting the purpose of the modernization effort.
Trump’s lack of understanding of fiber optic cables was immediately challenged by industry experts. Telecommunications specialists explained that the conversion from copper to fiber represents a necessary evolution in aviation infrastructure. Fiber networks are faster, more reliable, and less susceptible to electromagnetic interference—an essential feature for real-time air traffic management. Critics argued that Trump’s comment reflected a broader pattern of dismissing technical projects he fails to grasp, even when those initiatives have bipartisan support and proven safety benefits.
Trump Faces Backlash as Buttigieg’s FAA Reforms Gain Praise
Donald embarrassed himself by not understanding fiber optic cables when he again attacked Buttigieg’s FAA modernization program, describing it as “a bad deal mixing metals and glass.” His repeated misstatements about fiber technology came as the Transportation Department defended the initiative as one of the most transformative upgrades to America’s aviation system in decades.
Trump’s confusion over fiber optic cables did little to slow support for the FAA’s modernization drive. Aviation safety experts reaffirmed that replacing copper with fiber significantly boosts network reliability and security. “This is about performance, not politics,” said Dr. Laura Jenkins, an FAA technology consultant. “Fiber optics are the backbone of safe, efficient aviation in the modern world.” While Trump’s remarks ignited a wave of online ridicule, officials within the department remained focused on completing the nationwide conversion by 2027, underscoring that the president’s comments “do not reflect the technical reality.”
