Investigators believe a Cypriot Boeing which came down near Athens just over a week ago crashed because of low fuel and pressure. All 121 people on board the Helios Airways flight died in the accident near Grammatikos on August 14. The head of the investigation team told authorities they had found evidence of technical failure linked to low pressure. He also said it was clear the plane’s reactors had stopped functioning because the fuel supply was exhausted which was the final cause of the crash.According to the investigation, one passenger repeatedly tried to send an emergency message in the last 10 minutes before the plane came down. Helios Airways says its plane was airworthy, but Greek television claims the airline has a history of technical faults.
