Mike, these two shots were taken at La Aurora Airport, Guatemala. They swow an ENAER T-35A Pillan trainer and a Douglas DC-6 (TG-WOP), both belonging to the Guatemalan Air Force. They are beating the field down runway 01. The photographer is unknown, both photos are from my personal collection, having purchased them at La Aurora back in 2001.
TG-WOP is grounded due to main-spar corrossion issues, and was the largest airplane operated by the GAF.
Saludos,
Tulio
