In a few instances, situations arose when persons not familiar with the procedures and equipment used by the Balloon Branch misunderstood their activities. Such misunderstandings occurred several times during the 1970s and 1980s when recovery crews not only attracted the attention of local citizens while coordinating balloon recoveries, but also drew the attention of federal law enforcement agencies.[106] Checks with the local sheriff revealed that the trucks and circling aircraft in the desert near Roswell were part of a balloon recovery mission, and not a drug smuggling operation. Apparently, balloon recoveries appeared to be something suspicious even to federal agents. [Illustration: Fig. 61. A typical Holloman Balloon Branch recovery crew is shown here with a man known as “The hermit” who assisted them in a balloon recovery northwest of Silver City, N.M. in the 1960s.

A mule (named Ida) was borrowed from a local rancher when a balloon payload landed in difficult terrain 20 miles north of Wickenburg, Ariz. in October 1966.

This bulldozer was rented for one recovery in the Sacramento mountains west of Roswell. (_photo collection of Robert Blankenship_)] [Illustration: Fig. 64. Balloon Branch vehicle at roadside café. This M-43 ¾-ton field ambulance, converted by the Holloman Balloon Branch into a communications vehicle, was a common sight in the areas surrounding Roswell during the 1950s and early 1960s.

This question can be answered by comparing witness testimony and the Air Force projects of the 1950s, HIGH DIVE and EXCELSIOR. Both of these projects employed anthropomorphic dummies flown by high altitude balloons and appeared to satisfy the requirements of the previously established research profile: _a._ An activity that if viewed from a distance would appear unusual.
