Back in the early 80's I worked with a guy who had been an apprentice draftsman at Handley Page in Radlett, and the design office used to have a works outing to Farnborough every year. They went on the day the 110 crashed, and old Harry was standing with some of his colleagues in line with the oncoming DH110 when it broke up and he said he had nightmares for many years afterwards, as both engines came hurtling towards him, and he just threw himself onto the ground and they hit to the area about 100 yards behind where he had been standing.
He never attended an airshow again, and he had even decided to leave the aviation industry as well within a year.
