How much close formation time does one get in a generally autonomous data-linked stealth fighter?
Maybe criteria is involved, maybe not.
You know getting 'accepted' into the Buckley or ABQ or TUS Guard in the 70s & 80s was probably on par with the exclusivity of the demo team selections (minus the haircut requirement), but the criteria was heavily weighted toward pure flying experience and time in type. I happened to be at BKF for a drill weekend exercise when I saw 20 guys show up to interview for ONE slot. I don't think it was the sharpest looking, teetotaling family-man that was selected.
