Students at Millard West High School rehearsed for a situation they hope they'll never be in.
It was a disaster simulation, where every student involved had a role. some played dead, others acted out an injury before a first responder could get there and provide treatment.
"We really ask them to do a lot of acting, we didn't expect them to go as far as they did but they were screaming and crying and it was fantastic, says Brian Smith, emergency preparedness coordinator - CHI Health.
The strong acting by the kids allows the first responder team to be fully ready if a mass casualty situation were to take place anywhere in the Omaha area.
“It’s good that we know what we're doing and it's good that the people that take care of us know what they're doing and are really good at their jobs, says senior Abby Stevens.
Other students like Peyton Young appreciated the simulation but also recognize that nothing can completely prepare you for a real emergency.
"I feel like it would be more frantic maybe, but i don't know i've never been in that situation but it seemed really calm."
The first responders hope the students translate that calm demeanor if a disaster strikes for real.
