From: where I shouldn’t be
I don’t think that a wire would or could do the job. Take the max landing weight of a 743 of about 255 tons met. and add the pax martini factor all of which is coming to a stop within a few feet; that just might make matters worst. A bunch of airports has installed arrestor beds rather then wires. Some are made of natural material some have porous concrete. Either way the results and effects are the same. More often then not one can reuse the aircraft, pax walk of health- if even a bit through the wind, and the costs are "minimal".

Here is an interesting article I found on the net.


On Saturday, May 8, at JFK International Airport, a soft ground arrestor system developed by the Federal Aviation Administration safely stopped an American Eagle Saab 340, carrying 27 passengers and 3 crew, from possibly plunging off the end of the runway into Thurston Bay. The FAA developed and tested the arrestor system at the Tech Center and installed it at JFK under cooperative research and development agreements with Engineered Systems (ESCO) of Lester, PA, and the Port Authority of New York and New Jersey. According to preliminary reports, the aircraft, arriving in fog and light rain, landed long on runway 4 Right. It landed just 1,500 ft. from the end of the runway- 500 ft. beyond which is Thurston Bay. The aircraft
stopped 248 feet into the 400- foot long arrestor bed. All 30 onboard walked off the aircraft. Damage to the aircraft was minimal -- one bent prop and a couple of blown tires. All landing gear remained intact. The National Transportation Safety Board (NTSB) is now gathering data from the flight data recorder, which will give the aircraft’s exit velocity, enabling investigators to recreate the incident. The arrestor bed, installed in 1997, is constructed of
cellular concrete and is designed to bring transport aircraft to a safe stop in the unlikely event of a runway overrun. The cost to install the bed at JFK was approximately $2,620,000. Damage to the bed was restricted to a 30-foot wide and 250-foot long section. ESCO began repairs on Monday morning, May 11. The genesis for the development of an arrestor bed came in 1984 when a DC-10 aircraft overshot runway 4 Right at JFK and plunged into the bay. Although no serious personal injuries occurred, the incident resulted in $30 million in damages and prompted the NSTB to issue a safety recommendation to the FAA to ascertain whether an arresting system was feasible. The Port Authority has installed a second arrestor bed at LaGuardia Airport, and is in the process of installing a second system at that airport. The FAA has issued an advisory circular to provide guidance on the design of engineered arrestor systems, using knowledge gained from the design, installation, and monitoring of the JFK system
