The witness in the MSN story refers to an incident involving a Beechjet *nearly* hitting the fuel dump. I haven't found any online news related to that so we'll treat it as apocryphal, for now.
As a non-damage incident, it has not made it into the ASN database. User-added data is welcomed there but they do insist on reliable reference material like wikipedia.
This, for instance, was a Beechcraft Super King Air, not a Beechjet. It's unlikely that a spotter-ish witness would get the two muddled up.

In the meantime, I remain puzzled by the lack of eyewitness testimony from control tower staff but, if it is light on traffic, it may be an uncontrolled field, with ATC provided by Farnborough or another neighbour.
Can anyone clarify that point?
