I unfortunetly was unable to go this year - I have a number of colleagues there - and a number of our unit Reservists are there on TDY earning points. CAP is in charge of all the marshalling at Air Venture - under the designation "Blue Beret". The AF funded a brand new 60' tall RF antennae to support the CAP RF voice network for teh marshalling force (mostly manned by cadets). These cadets train for months learning how to properly marshall aircraft and direct planes to appropriate parking spots - think "yellow shirts".
While the AF has a very decent presence at Air Venture this year, AFSOC is deliberately making a marquis appearance - with 9 airframes coming to Air Venture from various AFSOC units - including the brand new C-145 Combat Coyote which will be both flight and static displayed for the public. The CC of AFSOC, Lt Gen Jim Slife will be there on TDY as well with his staff (apparently a great helo dude).
