Did anyone pick up, on the BBC challengers' debate a couple of weeks ago, that Nicola Sturgeon, whilst opposing Trident, said "we're a maritime nation and yet we don't have a maritime patrol aircraft - how ridiculous is that?"
On the face of it, she seems to have put more thought into defence issues than the others.
To be honest, regurgitating a soundbite she's probably been fed does not mean she could answer the question - "so what is a maritime patrol aircraft for"?
