Dublin 28 is a serious accident waiting to happen. Proximity to Pier 4, Links 1&2, E taxiways, short taxi routes, single runway ops etc. How many ground collisions have they had in that area?
OK, this time it was something different with a classic 'ready-for-immediate' combined with a bit of the ubiquitous RT faff. They're probably quite fortunate that the landing Ryanair decided not to go-around.
