I hear she ended up taking out some taxiway edge lighting and tore up the pavement a bit. Took a bit of an effort to push it back onto B!
There is no TWY edge lighting at BNE, the pavement was not torn up (TWY closed for a while pending engineering assessment) and it took no effort to push it back using the appropriate tug (issue is finding said appropriate tug and then getting it from effectively one end of airport to the other). I suggest you check your sources.
EK was not the first to overshoot B1 and they won't be the last.
I'm not sure why, but it is easy to do, it looks like the runway threshold is further down for some reason.
Can't see how this is so, as by the time you get to B1 the RWY 19 Threshold is effectively behind you. More likely they look up and see the RWY 32 threshold more or less directly ahead and just keep going.
