In 2003, aviator Dick Jackson completed an authentic restoration of the S-39, dubbed the Spirit of Igor in honor of the Johnsons and Igor Sikorsky. The restoration process required nearly 40 years and 40,000 man-hours to complete. It is currently the oldest flying Sikorsky in the world. The "Spirit of Igor" now resides at Fantasy of Flight Air Museum in Lakeland, Florida.
Another S-39, hull number 920, the last one produced, is currently under restoration in Southern California. Hull number 920 was originally owned by Shell Eastern, the original name of the Shell Oil Company.
