Yes it was. i was working there at the time and remember seeing the aircraft parked outside a day or so before the accident.
At that time new taxiways were being constructed onto the runway from the new terminal side. This involved night works between 2230 and 0600 hrs local weekday nights when the runway distance was reduced to 1500m. The runway edge lights at the time were elevated (they are now flush) and plastic buckets were placed over the elevated lights in the closed off area so they weren't visible.to pilots. On the early morning of 16th October '87 when the hurricane winds arrived many of the plastic buckets were blown off exposing the lights in the closed off area.! Fortunately no movements were expected until after 0600 hrs. Because the wind direction was south to south west and Stansted's runway direction being more favourable, a number of diversions from Gatwick and possibly other SE airports were received once the runway re-opened to full length.
