A  screen  was  hung  up  at  the  front  of  the  11-passenger  hydroplane,  and  a  DeVry
        Suitcase Projector was powered by the low voltage DC aircraft electrical system. (Pic
        8.) The DeVry Corporation went on to produce thousands of professional sound 35 mm
        theatre and portable projectors as well as making movie cameras.

                                                   One of their most famous news-
                                                   reel  cameras  was  the  square
                                                   ‘lunchbox’ model (Pic. 9.) and it
                                                   was an example of this tough little
                                                   35 mm camera that was chosen in
                                                   1947 to be installed in one of the
                                                   captured German WWII V2 rock-
                                                   ets for a test flight into the outer
                                                   atmosphere.  The  100  foot  film
                                                   was retrieved intact and gave the
                                                   first  real  view  of  the  earth  from
                                                   space.

                                                   So the DeVry Suitcase Projector I
                                                   first  saw  demonstrated  in  1964
                                                   has  a  great  pedigree.  It  is  worth
                                                   noting, however, that these small
                                                   machines still posed a significant
         Pic 9. The famous DeVry ‘Lunchbox’ 35 mm newsreel
                                                  fire risk due to the almost univer-
         camera.
                                                  sal use of highly inflammable Ni-
                                                  trate film base.

        So why was Nitrate in use even up to the 1950s? Simply put, because it was far more
        durable and scratch resistant than Triacetate ‘safety’ film. For professional exhibition,
        projection positives were carried between theatres on a very regular basis, and had to
        be speedily laced into the projector…they had to stand up to hard use.

        Safety Triacetate-based films were mainly used by amateurs in the smaller gauges. For
        this  fire  risk  reason  the  small  DeVry  suitcase  projector  was  also  lined  with  white
        asbestos but, even so, with the great heat generated internally, they could still burst into
        flame. According to veteran cinematographer Kev Franzi (who has recently restored
        one of these) the advice given to operators of the DeVry suitcase unit was ‘If a fire
        breaks out in the projector, quickly unplug the unit and take it promptly to the nearest
        window and toss it out of the room. Failing a window, take it outside to an open space
        to burn, all the while keeping calm and controlled so as not to stampede the audience.’
