RAF Cosford Airshow

[halfpenny43]

Hi all

Thinking over coming to the UK for the Cosford Airshow via the ferry to Harwich.

On the way back on the Sunday night - the boat leaves at 2300 UK and last check in is 2200 UK.
If I leave the show around 1630 and assuming traffic chaos - is 5.30hrs to do a journey that takes 3.30hrs safe ?

Never been to Cosford or any airshow in the UK for years and wondering what the traffic is like getting out ?

Anyone with experience - I would appreciate feedback

Thanks
