I have just checked my logbook. It was a Salmond Trophy Hi-Lo-Hi via Wainfleet range for a timed FRA. As previously stated the wx was total doggers. I remember the climb out from Wainfleet as being v turbulent and IMC with lots of St Elmo's fire all over the front of my windscreen. I was flying a B(I)8 from 14 Sqn. Radio reception was non existent because of the static. We did not know of the collision until after we landed. I think the 213 jet was either just ahead or behind us. Just bad luck and bad weather.
