Centrifuge rider sets endurance record
December 16, 1978, Discovery, Page 5
A human centrifuge record for endurance was broken last week by volunteer centrifuge rider, A1C Donald K. Adams of AFHRL. Airman Adams, a scientific assistant in the Computation Science Division of AFHRL, rode the centrifuge for 13 minutes and 49 seconds in a simulated air combat maneuver endurance profile. The profile takes the rider to 4.5 Gs for 15 seconds, then up to 7 Gs for 15 seconds, back down to 4.5 Gs for 15 seconds then back up to 7 Gs. The sequence is repeated until the volunteer is so tired he can't perform the straining maneuver well enough to maintain vision.



"The previous record for this profile was 11 minutes and 23 seconds," said Maj. Robert M. Shaffstall, of the Biodynamics Branch. "Most good riders average 5 minutes per run." The major said that Airman Adams went to 7 Gs 24 times during the record setting run. Airman Adams was involved in a test of a new anti-G suit for fighter pilots.

The Panama Chamber was constructed in 1903 and used at the construction site of the Panama Canal to treat decompression sickness. Believed to be the oldest hyperbaric chamber in the world, it is still in use at Brooks AFB (Brooks City-Base).

Established by Catholic religious orders to spread Christianity among local natives, five Spanish frontier missions are preserved in San Antonio, Texas.
Mission Concepcion
The Alamo (Mission San Antonio de Valero)
Mission San Jose
Mission San Juan
Mission Espada



Misión Nuestra Señora de la Purísima Concepción de Acuña was established in 1716 as Nuestra Señora de la Purísima Concepción de los Hainais in East Texas. The mission was moved in 1731 to San Antonio. Founded by Franciscan friars, this is the best preserved of the Texas missions. Located at 807 Mission Road, Mission Concepcion was designated a National Historic Landmark on April 15, 1970.





The Alamo Mission in San Antonio was originally known as the Mission San Antonio de Valero. It is a former Roman Catholic mission and fortress compound and the site of the Battle of the Alamo in 1836.



The Battle of the Alamo (February 23 – March 6, 1836) was a pivotal event in the Texas Revolution. Following a 13-day siege, Mexican troops under President General Antonio López de Santa Anna launched an assault on the Alamo Mission near San Antonio de Béxar (modern-day San Antonio, Texas, United States). All of the Texian defenders were killed. The Battle of the Alamo inspired many Texians—both Texas settlers and adventurers from the United States—to join the Texian Army. Buoyed by a desire for revenge, the Texians defeated the Mexican Army at the Battle of San Jacinto, on April 21, 1836, ending the revolution.



On the afternoon of April 21 the Texian army attacked Santa Anna's camp near Lynchburg Ferry. The Mexican army was taken by surprise, and the Battle of San Jacinto was essentially over after 18 minutes. During the fighting, many of the Texian soldiers repeatedly cried "Remember the Alamo!"
