You're both right. The '681 went through various evolutions before the Labour government axed it. There was a Pegasus VSTOL version (barking mad, in my view. Lift must exceed weight for VTOL - and where on earth would the necessary thrust levels to do that on a jet cargo aircraft be acceptable? ). There were other versions with Comet wings, C-141 wings...... All were much bigger than the BAe 146, incidentally.
