First of all, thank god J is making a full and speedy recovery. It has been no doubt a terrifying experience for him, his family and his colleagues and I hope he's able to get back in the air soon.
Had a look through the other photos of the recovery also Helimut, and I agree, the tail rotor must have not been rotating during the impact and roll-over. I also noticed that tail rotor drive shaft appears to be broken after the first visible bearing where the cowling had been opened. This can be seen in three photos but it looks like there is some thing extra around the shaft after the first bearing? Is it possible for a bearing to have come out of it's mount?
