(Another AV8RSTUFF Creation): This patch was created by the “FINAL CHECKERS” on the USS ROOSEVELT, but it applies to ALL the US Naval Aircraft Carriers. These guys are the ones who give the “FINAL OK” to launch an aircraft off the boat. It says “IF THE THUMB AIN’T HIGH, THE BIRD DON’T FLY” (top) and does not come with velcro attached.
