Piccadilly Lilly II is a B-17 Flying Fortress currently on display at the Planes of Fame air museum in Chino, California.

Her last mission was on August 6, 1959, when she controlled a QB-17G 44-83717 drone as a target for a Falcon air-to-air missile fired by an F-101B Voodoo jet fighter.

[4] In late 2008, the museum assembled a volunteer restoration team to accelerate the process of bringing B-17G serial number 44-83684, Piccadilly Lilly II, back to flight condition.

In 2009, significant progress was made with respect to the short-term goals of 1) enhancing the visitor experience and 2) systematically repairing and mitigating on-going degradation of structural components.

New gun barrels were fabricated and added to the tail and chin positions and a fully refurbished, modified top turret has been installed.

New signage (part of an Eagle Scout project) directs visitor attention to, and provides information about, various features of the aircraft.

Stripping paint from the nose and performing much needed repairs there will follow completion of the tail gunner and radio operator positions.

All props have been stripped and prepared for painting plus the tail wheel assembly and main landing gear have been cleaned and repainted.
