I’d probably go with the flare type system that’ proven and is lower maintenance. If a jet ever had to release flares on takeoff, you don’t think people at the airport would be going into code red status? They could get their fire teams out to the areas where they saw flares possibly going into neigborhoods or work with local fire departments. I mean even the laser system that confuses the missile - the missile has to go down somewhere too - and it could explode and start fires and damage buildings or houses, just like conventional flares can. Neither system is without risk to nearby houses and buildings.

You aren’t in Southern California are you ?
