Stark escapes and reunites with Rhodes, discovering that Killian intends to attack President Ellis aboard Air Force One, using the Iron Patriot armor, controlled by Savin. Stark neutralizes Savin and saves the passengers and crew, but cannot stop Killian from abducting Ellis and destroying Air Force One. They trace Killian to an impounded damaged oil tanker where Killian intends to kill Ellis on live television. The Vice President will become a puppet leader, following Killian's orders in exchange for Extremis to cure his young daughter's disability. On the platform, Stark works to save Potts, as Rhodes goes after the President. Stark summons his remaining Iron Man suits, controlled remotely by J. A. R. V. I. S. , to provide air support. Rhodes secures the President and takes him to safety, while Stark discovers Potts has survived the Extremis procedure; before he can save her, a rig collapses around them and she falls to the platform below, causing Stark to believe her dead. Stark fights Killian, but finds himself cornered. Potts, whose Extremis powers allowed her to survive her fall, intervenes and kills Killian to save Stark.
