It became a reality for one family on March 7.
But, thanks to the 911 dispatcher who picked up the phone, their child survived.
Scott Nelson was terrified when he found 3-year-old Piper in their pool.
Dispatcher Jennifer Gonzales instructed Nelson to give CPR until firefighters took over. Firefighters say it certainly saved her life.
Piper, Scott, Jennifer, Buckeye firefighters and the Native Air Ambulance flight nurse and medic who flew the little girl to a waiting hospital were reunited on Tuesday.
The week of April 12 is dedicated to National Public Safety Telecommunicators.
