This only happens at night, if we have the air conditoner on, after a few hours, our smoke alarm will start beeping in five minute intervals. We have four of them in the apartment and only one of them beeps. What could be causing this?
my parents had the same thing in thier old house water pipe coming from thier WELL. It didn't affect the water taste and no one got sick, but if you have concerns,send a sample to your state water testing facility
The missile system uses IR or Laser to lock onto its target and then notifies the pilot that it is locked. Once locked, the pilot can deploy the missile. On the new F-22 he can lock on multiple targets at once and choose his targets. Once the missile is launched, it has its own onboard control and targeting systems to find the target and the pilot is free to move on to his next target.
