Crew members from Offutt Air Force Base’s 55th Wing feasted their eyes last week on something they hardly ever get to see: a new plane.

Well, sort of new.

The WC-135R “nuke-sniffer” jet that landed last Monday at the Lincoln Airport — the 55th’s temporary operating base while Offutt’s runway is replaced — was actually built in 1964.

But the former aerial New Hampshire Air National Guard refueling tanker has been refitted with new equipment capable of detecting atmospheric radiation, and updated with modern “glass cockpit” controls. And it has the same newer, quieter turbofan engines as the rest of Offutt’s RC-135 reconnaissance fleet.
