Professor Philip Nolan:

Honestly, I think it is possible but it would be arrogant of me. We cannot predict the future and people who do my type of work and the type of work Dr. De Gascun does need to be humble. There is lots we do not know. Right now, on a precautionary basis, we need to plan as if it is possible and ensure that we have all of the contingency plans in place to deal with a tough scenario should it eventuate in the future.
