The evacuation followed a fatal runway incident days earlier in which a Frontier jet struck a trespasser who had breached the airport perimeter, prompting an emergency slide evacuation. The National Transportation Safety Board began reviewing the incident, intensifying scrutiny of Frontier operations at Denver.
Timeline of the Evacuation
8:08 p.m. (Sunday) – Flight 4765 scheduled for Phoenix. Shortly before take-off – Ammunition magazine discovered. After discovery – Passengers deplaned; security sweep performed. Overnight – Crew exceeded duty-time limits; passengers rebooked. ~6:00 a.m. (Monday) – Re-scheduled flight departed DEN. 6:50 a.m. – Arrival at Phoenix.
Flight Details and Operational Impact
The plane carried about 231 passengers. The delay forced the crew to exceed duty limits, leading Frontier to reassign travelers to an early-morning flight. Passengers received a $15 voucher; full-refund requests were denied.
Official Statements and Responses
Frontier spokesperson Rob Harris said the magazine likely belonged to a law-enforcement officer who left it on a prior flight and that passengers were deplaned “as a matter of precaution.” Denver Police confirmed the FBI is leading the investigation. The TSA said it was aware of the incident. A Denver airport official said only flight 4765’s passengers were affected.
Criticism & Opposition
Passenger Rashon Hammonds said communication from airline staff was limited and expressed dissatisfaction with the $15 voucher offered, noting that full refunds were denied. A TSA union spokesperson wrote, “Finding a magazine on a plane means we missed it. Not good,” criticizing the security screening.
On-the-Ground Reports
Hammonds said after deplaning passengers were escorted back to TSA checkpoints without clear instructions on whether to re-enter the terminal or await a new flight.
Conflicting Reports & Gaps
Authorities have not clarified how the magazine entered the aircraft, whether it was in checked or carry-on baggage, or the exact moment it was found. Frontier’s suggestion that it belonged to a law-enforcement officer remains unverified.
