I was looking through some photos on the database of the Global Express. This was one of the reamarks on the photos, "C-FKGX (cn 9004) back at home. This is the AC was flown at over the speed of sound during tests. Also can cruise at .98 @ FL510." I dont doubt that it was flown over Mach 1.0 in tests. But cruise @ Mach .98?!? I thought the Citation X was the fastest Biz Jet @ Mach .92, am I wrong?
