I have just come back from Charlies memorial at VRD. He was agreat bloke and will be sorely missed by all who were lucky enough to know him. Early reports have said they fell vertically from 100'. Photos ive seen seem to support this, but i am no expert. Overpitch, Vortex Ring, Bad auto ? Hopefully we will find out in due course.
Our thoughts really are with his family.
RIP - Charlie Chambers - we won't forget you.
