"Thirty Seconds Over Tokyo" and "Thirty Minutes Over Oregon"

My 10-year-old was reading Nathan Hale's Raid of No Return (Hazardous Tales #7) and texted me this:

Yes, it is no coincidence...Thirty Minutes Over Oregon: A Japanese Pilot's World War II Story, out 10/9/18, explains the connection.

By the way, take my son's lead and read Nathan Hale's Raid of No Return. It is so well done.
