Arrestor Systems
Centaurus says a number of years ago he tried to convince the Essendon authority that it would be sensible to install Arrestor systems on the West end of runway 26 and the South end of 17. His suggestion was not taken up.
It is still very much a good idea. The current technology involves "lightweight crushable concrete blocks, similar to a runaway truck ramp, and if properly designed can substitute for a runway safety area, or RSA"
In the US the following aircraft found the arrestor system handy:
May 1999, Saab 340, with 30 souls on board
May 2003, MD 11, cargo, 3 souls
Jan. 2005, 747, cargo, 3 souls
July 2006, Falcon 900, 5 souls
July 2008, Airbus 320, 145 souls on board at Chicago
Jan. 2010, Bombardier CRJ 200, 34 souls
Oct. 2010, G-4 Gulfstream, 10 souls
Nov 2011, Citation 11, 5 souls
Oct. 2013, Citation 680, 8 souls on board
I bet that you could build a runaway truck ramp for a fairly reasonable cost...
