Interesting. Navy Blue Angels AND Air Force Thunderbirds together. Search MIL Air and the top end of Civilian Air.
The last time I saw the Thunderbirds at an air show more than 25 years ago, they were using 141.85MHz AM. Also on 413.xxxx MHz NFM. I don't remember the exact 413 MHz freq but it was used for ground ops.
On 141.85 AM:
"Right turn NOW."
"Smoke start ready NOW."
"Smoke stop ready NOW."
"Little more roll.....little more roll...."
Mostly synchronization commands on 141.85 AM. This was more than 25 years ago so they might be using something different today.
According to the Colorado Forum (where they did a fly over recently), they were active on both 141.175 and 141.850. I also noticed from my notes several years ago, I heard them on 141.175 at an Atl City air show.
