Well, there are indeed informations coming about the damage to the undercarriage of this aircraft in Kraków. From my point of view, nobody is perfect and things could happen. But why there must always be somebody else to blame? According to ryanair.com
1130 FR 2433 Krakow - London (Stansted) DELAY
Eta 1230 air traffic control departure restrictions at krakow airport
Can this kind of incident be called air traffic control restriction? Btw., ETA is a bit over-optimistic, isn't it?
