Over the last past two weekends, Mohave County residents were treated to a rare view of the B-17G Aluminum Overcast that touched down in Kingman and Lake Havasu City for a display.

Including the Aluminum Overcast, it is estimated that there are only 46 B-17s in existence today and only 11 are airworthy in the U.S., and the B-17G Pink Lady in France and the B-17G Sally B in United Kingdom are also airworthy. Of the remaining 46 B-17s, some are currently under restorations throughout the world; some are only museum displays and are unable to take to the air.

The 13 airworthy B-17s are:

• B-17F Boeing Bee owned by the Museum of Flight in Seattle, Wash., is airworthy, but remains stored;

• B-17G Madras Maiden owned by the Erickson Aircraft Collection in Madras, Ore.;
