How was Flydubai co-pilot cleared despite being deemed a security risk?

A Flydubai co-pilot accused of attacking his captain with an emergency axe and attempting to seize control of the flight bound for Israel had previously been barred from flying over concerns about alleged “extremist” views, raising questions about how he was allowed to fly to Tel Aviv. The co-pilot has been identified as Hamam al-Hammami, an Omani national, according to multiple media reports. The United Arab Emirates (UAE) has described the September 30 incident aboard Flight FZ1073 as an attempted “terrorist” operation . But investigators are still working to establish the motive and whether anyone else was connected to the attack, which has raised concerns about pilot vetting and aviation security.
