The sentimental old fool in me says "Yes, what a brilliant idea, go for it and we'll all come and help you make a go of it...."
The realistic cynic says, "Yes, go for it, it will cost you £thousands, you'll never get a commercial return, even if you do get past the planning and NIMBY process, you'll always be faced with aviation and non aviation people just waiting to trip you up (believe me - they are there in equal measure), and you'll probably regret ever having such a daft idea until such time as you sell it for building land, make a million, lose all your friends and move to a hot sunny island with a list of select Bimbo's".
A difficult choice.
