James Albert Jackson Carroll, (April 4, 1902 Belton, Texas - July 17, 1987 Tujunga, California joined with Williams to form the Texas Aero Corporation, the 1st commercial aircraft fabricating facility in Texas. Williams and Carroll designed and built the "Temple Monoplane" to deliver newspapers and mail to remote counties in the Lone Star State. 

 None of the original aircraft remain in existence today, but an airplane restorer scavenged the former sites of Texas Aero to come up with enough cast out and extra parts to build a flying model of the Temple Monoplane. This airplane is now on exhibit at the Frontiers of Flight Museum at Love Field in Dallas, Texas. In 1970, a commemorative plaque was placed by the State of Texas on the site of the original hanger of the Texas Aero Corporation honoring the pioneers of Texan aviation, including credit to George Carroll. According to the Temple Daily Telegram, the plaque was reportedly stolen sometime between 2004 and 2007.The plaque was replaced in 2010, with a dedication celebration for family members and descendants of the aviation pioneers and the public.
