my guess is this
the approach was not going well, drifting off localizer perhaps...but then the pilots saw the runway and ''went for it''. But as we all know, there is many a slip between the cup and lip.
Did they over bank to get to the runway and drag a wingtip along the runway lights?
Of course if they had ''gotten away with it" without damage and an on time arrival, no one would know except the captain and the f/o.
There are pilots who are not experienced and pilots that are very experienced...there is also the rare pilot who thinks he is the later but really the former. Granted, if the plane is one second away from burning up in the sky...you go for it...but that lucky attempt usually uses up all your luck for a career.
still not as bad as delta landing on a taxiway!
