The Seven tried to rescue hostages from terrorist who have taken over a flight. With no training in crises like this, or even a plan on how to rescue everyone, the Seven simply charged into the plane while it was up thousands of feet in the sky. They caused several civilian casualties on their own, and having killed the terrorists, they discovered that their only member who knew how to fly a plane, Black Noir, was not with them aboard the plane.
Homelander then decided to leave the hapless civilians to their own fate and escape.
