Sad news indeed.
Like many others I owe in part my current lifestyle to Jonesy persevering with me on the IR course. I remeber well the comments about using one's feet and even now as I wander across the North Sea I say to myself 'Fly Accurately'! That one was drummed in to my head.
Thanks Jonesy you'll be missed. Deepest sympathy to his family and RIP.

P.S. His anecdotes ought to be collected on pprune!
