Thanks for your post. Please understand that in view of the very sensitive time for Dave's family it is not fair to pass comment in public or to indeed report on the actual sequence of events leading up to this tragic accident. Please respect this.
Please do not speculate, it’s not helpful to Dave or his family at a very tough time for them. All I can say is that at this stage all the people who NEED to know have full knowledge.
I'm sorry to not be able to say more, but please respect the spirit that this post is made in.
In the fullness of time full details will be posted - now is not the appropriate moment.
