When is anyone going to start shedding light on the fact that Sikorsky didn't really break any record? If you want absolute with a plane jane fling wing, the Lynx got it... Absolute with any assistance, the 533. Otherwise I am going to start setting records for absolute groundspeed with a tailwind, fastest speed over a 20cm course, hell the world record speed with autopilot on... and feel legit because the claim the X2 is now the fastest thing with a rotor system has not been called out. Nothing against the program; Sikorsky is very smart perusing the whole ABC/Aux Propulsion thing as it is one of the futures of rotorcraft and it is very admirable that they are doing it all on their own initiative (and dime)... but the fanfare is going a bit too far and they are greedily overshadowing a lot of the other notable advancements in helicopter history for the sake of publicity.
