While many of us were sleeping peacefully last night a team of workers at Gatwick had their noses well and truly to the grindstone.
The diggers were out in force as the crew began the arduous task of resurfacing the airport's main runway.
Gatwick's the busiest airport in the world and used by more than fifty planes an hour.
It's so well used, the runway has to be resurfaced every twelve to fifteen years.
Last night's task was one of six months of overnight sessions to complete the job at a cost of fifty million pounds.
Our Transport Correspondent Mike Pearse watched the work unfold and chatted to Derek Hendry about the job.
