Capt Smit Machchhar, speaking from a hospital bed in Abu Dhabi in an interview with The National newspaper, said he initially thought something had gone "horribly wrong with the aircraft structure" when the first blow landed, before realising he was under attack and that things had "taken a drastic turn".
"The next thought was I need to get help in here," he said. "My immediate action was to free myself from the seatbelts and I tried to just block the blows as much as I could."
Pointing to his wounded arm, he described how the blows came to his head, and that he reached for the door release and screamed for his colleagues. He said he believed that was the first time he lost consciousness.
The attack took place on flight FZ1073 from Dubai to Tel Aviv last month while the aircraft was in Saudi airspace. The co-pilot, an Omani national, is accused of attacking Machchhar with a crash axe kept in the cockpit for emergencies. The plane plunged 16,000 feet in about 30 seconds before the attacker was overwhelmed and two other pilots on board landed the aircraft safely in Saudi Arabia.
The suspect was transferred to the UAE, flydubai's home country. UAE public prosecutors said their criminal investigation, launched on 1 October, had concluded the plan was inspired by the 11 September 2001 attacks on the United States.
Machchhar said he heard the cockpit door opening and screaming "between my colleague and the guy". He described the aircraft's nose "steeply going down" as the scariest moment. "I was not very sure that I'll make it out alive from this. Did I give up? No."
