| Aviation experts say corrosion could have been enough to have caused the 2.5-3m hole in the fuselage - if even a small section of the plane's aluminium skin was able to break free, the enormous pressures generated at cruising altitude could have done the rest. | Aviation experts say corrosion could have been enough to have caused the 2.5-3m hole in the fuselage - if even a small section of the plane's aluminium skin was able to break free, the enormous pressures generated at cruising altitude could have done the rest. |
| Other possible causes might include accidental external damage to the plane on the ground, or something inside the plane which had not been properly secured and slammed into the fuselage at some point. Investigators will want to rule out the presence of any explosives. | Other possible causes might include accidental external damage to the plane on the ground, or something inside the plane which had not been properly secured and slammed into the fuselage at some point.
