LGW Closure?

[bruppy]

just after midnight we were informed that LGW was closed for traffic? Nearly got a sweat on as i thought I'd have to do some work.
Airport open again after about an hour (+ no traffic my way, Phew!!) but no explanation given?? Any idea's:confused:

Apparently an hydraulic fluid spillage, allegedly from a Thomas Cook
B757.
