Wow, some comments! stage 3 burner, must be a squid thing. The F-15 has 5 stages of augmentor, not afterburner. Also the run was done inside of a hush house, which is where most high power runs are done, and you can hear the engines running outside. I only ran an engine testing facility at Eglin AFB for 2 years, so I know a little about them.
