Oklahoma City used to have a KILLER airshow, but I don't know if they do it anymore.
Yes, they still do, it is called AeroSpace America and it is always on Fathers Day Weekend. What better time to have it!
However it is no longer at Will Rogers World Airport after Tom Jones was killed. He was killed in a crash of his high-technology Sukhoi Su-26M aerobatic plane in front of 75,000 spectators on the final day of Aerospace America '90. Only five days before the accident, Jones, known and respected worldwide for his professional aerobatic skills and engaging charm, called the airshow "the greatest thing that ever happened to Oklahoma City." He was also IIRC, the founder of AeroSpace America. His wife took control of the airshow for several years, but after that tragic event, they lost money and had to move it to other airports in Oklahoma City. It went to Wiley Post Airport for several years but since that airport was small, there was less displays and people showing up. It eventually moved to Tinker Air Force Base where it is still done there today.
