At the time o was residing in the Eastern end of Staines ( now on Thames ) neat the Crooked Billet ( now gone ) and iirc we were on a walk through the park backs to where the accident occurred and heard but not seen the crash. .Within 20 minutes the area was swarming with blue lights .. then the smell of unburnt fuel hit us. Never to be forgotten ..
Always even now look over from the Southbound M25 when passing the A30 junction towards the power pylon
