However, The Aviation Herald says a bird strike was ruled out “due to a lack of blood, feathers or any other bird remains.”
A couple of pilots on The Aviation Herald website have commented that they experienced similar situations.
In those cases the damage was due to a damaged radar in the cone, causing the nose cone to collapse.
According to The Sun, experts concur the damage was not due to a bird. They say the plane’s elevation was too high for birds, and suggest another possibility could be a drone. The Sun says Chinese authorizes have yet to officially respond on the cause of the accident.
