As far as I am aware, the K3's have better (at least on paper) landing capability, allowing it to land on a shorter runway than a C1K.
As the short runway at Cosford seemed to be the issue with getting Bob in there, hopefully this will be beneficial to an effort to get a K3 there.
Now, here's the bit we need to do.......get writing letters! Send a letter to your local MP asking what the government/RAF is doing to preserve the last wholly British built 4 engined jet airliner.
I am going to be writing to my MP and suggest everyone else does the same!
