I don't know why the pilots landed the way they did but the structure was there for a valid reason. It's the runway localizer antenna. It was elevated off the ground to protect it from flooding. Should it have been frangible, yes, but it's not at all out of the ordinary as far as structures near runways go, and I think the focus on it is sensationalist and misguided.

By structure I meant the dirt mound with a concrete wall inside it, not the localizer. Entirely normal to have a localizer, but usually on a frangible structure if it needs to be elevated.
