Monday night, 10News talked to experts to learn more about how people can prepare for this kind of situation. If something happens and you need to evacuate quickly- our expert says the middle of a crowd is the worst place to be. If you can, get to the edge of the crowd.
Wayne Spees specializes in threat assessment and training for Workplace Guardians . He's an expert on how to react during an attack similar to that in Manchester.
"Getting trampled or crushed to death is just as big a threat as the attack itself," Spees said. "The best thing is situational awareness, and recognizing when something is wrong and reacting to it, don't just sit there in denial and hope this doesn't happen."
Spees said that seconds could make all the difference when it comes to survival.
"We have a few precious moments...to do something and react, so if that's creating distance between you and the threat, you should be doing that," he said.
Spees says it's important to get as far away as possible, but sometimes the only way to do that is to be prepared.
"If you're close to the aisle and something happens, you're going to have access to that aisle more quickly and you're going to get out a lot faster than someone who's seated in the middle," he said.
Once you get out- Spees says to avoid big crowds and stay calm - because you don't know if the attack is over yet.
Another important thing to remember - have a rallying point. Know exactly where you plan to meet if you become separated from friends or family during the chaos.
For many, the impulse to try and call someone is irresistible, but when thousands of people are on their phones - you may not be able to get service. Texting may be a better way to communicate.
