Flew a demo trip for Netjets last week. Picked up a couple famous faces and took them from ICT-CMH. Every piece brought on the plane had Learjet 85 on it. Very dependable source quoted 100 aircraft deal done by the end of summer.
That Lear 85 looks like a sweet ride with a nice office for those up front:

If it becomes the replacement for the Soveriegn, I know a C680 pilot at Netjets who will be happy - he is not a fan of the airplane or the Primus Epic up front. Nice to see that avionics continue to evolve - I love that synthetic vision.
