Runway, that has been stated several times over.
Anyway, I very much doubt Ryanair will take up BHX from Knock, as Shannon supported over 100 daily seats to BHX on expensive tickets. Knock wasnt so lucky.
With a larger market and lower fees at Shannon, you can be guaranteed that FR will not be taking up BHX from knock without them picking it up at Shannon first.
Meanwhile, 4 flights heading to Knock diverted to Shannon today. 3 of them flights returned to Knock and did the return Journey, and the other 1 flight to London Stansted took off with passengers transferred from Knock transferred by bus to Shannon.
A new charter to Turkey runs next September/october bookable through Sunway.ie
