If I you're landing with no flaps I very much doubt anyone would select BLK to land there unless there was an absolute dire need to get on the ground and even then it's likely they would have over-ran. By a LONG way.
MAN is just down the road with two nice longish runways. PIK is up the road too. So I doubt very much this was a flight control or flap/slat issue although I'm happy to be proven wrong.
