| Sep 16, 2019 at 3:38 | comment | added | jwenting | @LawnmowerMan making the cables much longer (like in kilometers which is what airliners need to stop) is impractical at best. Cables are in use for emergencies at some military fields, and they're not significantly longer than those at carriers. They're only used in emergencies as there's almost guaranteed damage to the aircraft and pilot when they are used. | |

This isn't the main reason not to implement such a system - if it were otherwise profitable and sensible this requirement could easily be accommodated. | |
