• Flydubai co-pilot accused of attempted axe attack had been deemed a security risk.
• Co-pilot had previously been barred from flying in Oman due to extremist views.
• UAE describes incident as attempted terrorist operation.
• Investigation raises concerns about pilot vetting and aviation security.

This incident may indicate a gap in aviation security protocols, suggesting that current vetting processes could be insufficient. The fact that the co-pilot was cleared despite being deemed a security risk may signal a need for more stringent background checks, which could impact the hiring processes of airlines and the overall safety of commercial flights.
