I think the helicopter was damaged before at some time in its life, it was then sent back to Robinson to be repaired and possibly zero timed.
On a more worrying point I believe the pilot and passenger had their clothes removed by the police for forensic investigation before they were airlifted to hospital can you believe !!! and the pilot was not allowed to retrieve his telephone or car keys from the damaged machine as the police deemed the crash a "crime scene" he might get them back tomorrow. I was also told that the police wanted to take him to the station for a statement before he went to the hospital!
I think the airport has just reopened this afternoon after nearly 2 days because of the "crime scene"
I dont know about you but since when did having an innocent accident while taking off become a crime !!!!!!
