however well you think you know the area
I knew the area extremely well - departed Manchester International, found the telescope, followed the railway to Crewe, turned right found my way to Chester, saw the river Dee between Wales and the Wirral (which clearly marked the edge of Liverpool airspace).
Easy this - up the river, turn right across the top of the Wirral, re-enter Manchester from the North West - job done.
Happily flying up the river Dee looking at the river banks...the cross river ferries, the Liver building....
The cross river ferries and The Liver building?
There's only one river that has a ferry 'cross it and we all know the words to that song.
Liverpool Approach forgave me because I jumped on the radio and admitted my mistake - didn't try to hide it.
Not a proud day.
