New reports on airport flight display system details its design

New information is out about the flight display that fell and killed a ten year old boy. ABC 33/40 now has more than 1,000 pages of documents about its construction. The documents - released Thursday- detail the design, construction, and installation of the "flight information display system."

While there are still many unanswered questions about how that display cabinet was built and why it fell, the 1,247 pages are giving us a better picture of how it was made. It's been just over a month since a flight information board at Birmingham's new airport terminal fell- killing a 10 year old boy traveling with his family from Kansas. Why that board fell {}is still unclear but newly released documents {}are giving us an idea of exactly how that cabinet was built.{}We poured over the designs with an engineer and here's what we found:In one part of the plan, the display system appears to be {}"portable" with "minimal hardware and software overhead." But in another section, the design plan - dated after the accident - calls for a "wall brace" with brackets and bolts going through the wall it sits against.The design shows wall mounts at four locations behind the cabinet holding it onto the wall of the airport. Other documents show the display system was smaller than the design called for and may not have required additional bracing. Brasfield & Gorrie in early statements regarding the accident, say the Birmingham Airport-Authority did not have knowledge of any ''stability'' concerns involving the information display. They also told us the cabinet was designed to be free standing. The attorney for Fish Construction which built the cabinet but did not design the cabinet says {}the company had expressed concerns over the stability of the display to contractors "KPS" and Brasfield & Gorrie before the unit was installed.
