Co-pilot hijacks Ethiopian Airlines aircraft Swiss authorities have arrested the co-pilot of an Ethiopian Airlines flight that was forced to land at Geneva's international airport. Geneva airport chief executive Robert Deillon told reporters on Monday that an Ethiopian man took control of the plane when the pilot ventured outside the cockpit. The co-pilot himself alerted authorities to the plane's hijacking, officials added - though passengers on the plane were unaware it had been hijacked. All 202 passengers and crew on board were unharmed. The co-pilot could be charged with hostage taking which carries a prison sentence of up to 20 years, according to prosecutors.
