kevin, sorry, but I didn't know Van Jacks,,you gotta remember, there were a lot of JO's at Jax back then - 7 squadrons including VP30.
Several guys from my squadron went to VP31 you may have crossed paths with; Joe Fricke, Chuck Mercer,,. James Wilkerson went to Wing One ASWOC there at Barbers. He was probably your DBO a time or two.. losing the medical was tough but the FAA has been great. I've been working the ADS-B program these last 4 years now. I think most of the UPS fleet are equipped - a lot of work (and $!) went into STC's and equip for those freighters. stay safe, Charles
