Retired Tech. Sergeants, Ron Tidwell and Scott Harrington, now M-1 Support Services contractors, prepare to inspect a B-1B Lancer before takeoff at Ellsworth Air Force Base, S.D., May 10, 2011. Mr. Tidwell and Mr. Harrington share a combined total of more than 40 years worth of B-1B mechanical experience, reducing the amount of time it takes to prepare jets in half.
