Hyde Park is major park located in London.
During the London Siege, terrorists working for arms dealer Aamir Barkawi shot down Marine One after Marine Two and Marine Three were shot down, leaving Marine One defenseless. Marine One crashed into Hyde Park and Secret Service Director Lynne Jacobs was fatally injured.
Before she died, she told Mike to stay alive to see his unborn child and to make the terrorists pay for their actions. Mike Banning and U.S President Benjamin Asher were forced to flee the crash site after terrorists closed in on the scene.
