Passengers are struggling to believe it: a pilot who spent nearly two decades in the cockpit of Air Canada aircraft is accused of flying hundreds of commercial flights without holding the licence required to serve as a captain.

Canadian authorities allege that Geoffrey Wall worked as an Air Canada captain for 17 years despite not possessing the mandatory Airline Transport Pilot Licence (ATPL). Investigators claim he flew more than 900 flights before the alleged discrepancy came to light.

The revelation has stunned the aviation industry, particularly because Wall reportedly passed regular training exercises and competency checks throughout his career. Air Canada says he held a valid commercial pilot licence but not the qualification required to command large passenger aircraft as a captain.

While authorities have stressed that there is no evidence passenger safety was compromised, the case has sparked widespread debate about how such an alleged oversight could have gone unnoticed for so long. Wall now faces fraud-related charges as Canadian investigators continue to examine the circumstances surrounding the case.
