Derry Closure
It sounds like from the airport website that the airport is closed for safety reasons. It must be severe enough to warrant closure - thats quite extreme and unusual.
if it's long term it spells ruin to Loganair's flights. Surprised Ryanair wont use BFS in the interim until something is sorted. EG in the case of Weeze they used Eindhoven but not in this instance. They either dont want to get into a head to head with easyjet or they wont do business with BFS. Perhaps tomorrow there might be positive developements. I have a friend working at the airport I must chase up to find out some info.
