E-2 New York f;K'- when the experimenter breaks tlie balloon. Marvin admits that he likes it but doesn't want any of the bigger balloons broken. When asked what he would like to do with the bal- loons, Marvin says that he would like to take them home but c;in not demonstrate how he would like to play with them. Ot one thing he is sure—he doesn't want them broken. Terry is now introduced to exactly the same situation. Upon entrance into the room he is intrigued by the balloons and can't keep "hands off." He bats them into the air, and immediately accepts th' invitation to break them. By standing on them, rolling on them, squeezing them, and using the assistance of the experi- menter, Terry finally succeeds in bursting every balloon in tl e room. Committee .Apprais.-m. : The film is valuable to demonstrate the existence of individual differences in the amount of hostility or aggression present and the control exercised over it in indi- viduals. It is an excellent film for use by classes in psychology, teacher-training, and in P.T.A. groups. Groups will vary in how they will account for the differences in behavior shown in the film and in methods for assisting youngsters displaying these beliavior patterns in making social and personality adjustments. Construction oi a Light Airplane (The Pennsylvania State College, State College, Pennsyl- vania) 28 minutes, 16mni. sound. Sale price $40.00 with reel, without can. .^pply to producer, .Attention I. C. Boerlin, for rental sources. In an introductory sequence from a working model of the nnder-fabric structure of a small airplane, the five major parts of an airplane are functionally identified. The steps in the construction of an actual fuselage from chrome-molybdenum steel tubing are then shown. The operation of specially de- signed machinery, such as the nibbling saw for shaping the ends of the tubing, is shown in detail together with the as- sembling of the parts in a jig for tack-welding, the final welding operation, and the addition of "fahrings" to give optimum shape for best performance. The fuselage is then shown being primed with zinc sulphate for protection and finishing. On the completed fuselage under-fabric structure, cables, cabin fittings, control stick, rudder bar, and steel fire walls are seen being mounted; and finally the covering of the fuselage with a strong mercerized cotton fabric shrunk into place and finished with many coats of cellulous airplane dope is shown. The construction and operation of the shock-absorbing land- ing gear is explained and demonstrated and the landing gear assembly is shown being fitted with rubber shock cords be- fore being joined to the completed fuselage. Next, the tail surface steel sub-assemblies including elevators and rudders are shown being completed, joined to the fuselage, and con- nected to their respective control cables. The construction of the wing ribs from drawn aluminum shapes and their assem- bly to spruce spars and bracing with compression bars and tie rods; the installation and protection of aileron control cables; and the covering and doping of the completed wings together with the final assembly of the wing to the fuselage are seen. Finally the construction and assembly to the wing of the ailerons, the mounting of the engine and propeller, and the installation of the cowling are shown, and the completed airplane leaves the factory for adjustments and tests. The procedure for compensating the magnetic compass, and the air tests for stability and safe operational performance which the plane must pass in order to be licensed are demon- strated. Committer Appraisal: This film follows the actual con- struction of a "Piper Cub" with meticulous detail. It would be especially useful in adult and high school pre-flight courses to familiarize students with nomenclature and appearance of the constructional details of an airplane and in vocational guidance groups for illustrations of various skills required and types of work done in airplane manufacturing. Since the film is confined to a single manufactured design and construction, the instructor may want to supplement the film with information on other types of light airplanes. In the opinion of the authors this is the best film that has been sub- mitted for use in pre-flight courses.
