Theodore “Dutch” Van Kirk, the last living crewman and navigator on the Enola Gay, the B-29 that hastened the end of World War II by dropping the atomic bomb on Hiroshima, Japan, will autograph copies of his biography, “My True Course: Northumberland to Hiroshima,” on Saturday.

The book-signing will take place from 1 to 4 p.m. at Executive AirShare, Buffalo Niagara International Airport, 485 Cayuga Road, Cheektowaga, Hangar Bay No. 7.

“My True Course” is a hardcover, 578-page book with more than 100 images. It includes unedited correspondence to and from home during the war and the entire navigation log of the Enola Gay’s Special Mission No. 13.

The author, Suzanne Simon Dietz, is historian for the Town of Porter in Niagara County and the Aero Club of Buffalo and is a researcher for the Niagara Aerospace Museum.

Van Kirk, who lived and worked in Niagara Falls in the early 1950s, was a lead navigator in bombing raids in Europe and North Africa.

He then was chosen as lead navigator for a composite group in the Pacific, leading to his assignment to the Enola Gay.

Sales and advance reservations for copies of the book are being handled by The Book Corner Inc., 1801 Main St., Niagara Falls. The cost is $40 per book, including tax.
