Busy sky

Seems I'm rather late in putting up my blip of this morning's sky with its amazing display of vapour trails, that inspired so many blippers.   I am in Essex, so Stansted is the nearest London airport to us, but we see plenty of action from planes going to and from the other London airports.
When I woke around 6am the sky seemed especially dark:  this was due to the heavy cloud cover which gradually moved away.  You can see the receding cloud bank just above  the rooftops.
Sadly, the sky is now back to the all too familiar grey!
