Narrative:

I have noticed driving to the bwi airport passing runway 10 approach lights; a massive metal structure being built between the approach lights. It is just below the approach lights plane. It appears to be a very rigid structure that would severely damage an aircraft if it ended up below the glide slope. Maybe wind shear. I remember a B747 that took off from sfo on the wrong runway. The runway was shorter then planned. When it rotated it was flying in ground effect and took out the approach lights at the far end. The approach lights were not installed on a break away structure; but metal i-beams that did major damage to the aircraft. Do we want a major metal structure on short final to runway 10?

Title: Air Carrier Captain reports that a large metal structure is being constructed off the approach end of Runway 10 at BWI that would increase the damage to an aircraft landing short of the runway.
