I have a supervillain in my story that can fly at speeds up to Mach 2. For obvious reasons, this character does not want to be detected while flying. However, I am facing writer's block and cannot think of any way for this character to remain undetected by citizens and government officers alike.

- This character is allowed to use any piece of technology that currently exists but not any form of Clarktech.
- The story is set in modern-day America.
- The character uses iron-man-like fire thrusters to fly which as you can imagine are pretty bright.
- Nobody knows superpowers exist in the story yet.

Edit: The character is a pyrokinetic and shoots super hot fire out the back of their legs to fly. Additionally, this character is flying over new york at night.
