I turned around and took off IFR just in time to hear a G reg homebuilt flying back VFR to the UK.
He was following the beaches past Le Touquet and had been forced down to below 200 feet. He was navigating using the sea/beach line. I had him on frequency listening to his progress as he turned towards the UK. Halfway across the channel I was relieved to hear he was climbing to 700 feet as the cloudbase had improved.
That may not be weather you would dream of flying VFR but this guy was and there are a surprising number who do get up to antics like that.
He was obviously illegal but he would have been a lot safer had he climbed up and flew VMC on top (assuming cloud tops not too high etc). That's what I used to do before I got my IR.
