I fixed a small problem. Vtol up to fold, keep at 20 percent power. The DeLorean time machine is a fictional automobile-based time travel device featured in the Back to the Future franchise. In the feature film series, Dr. Emmett Brown builds a time machine based on an automobile; a DeLorean DMC-12, with the intent of gaining insights into history and the future but instead winds up using it to travel across over 130 years of Hill Valley history (from 1885 to unspecified points beyond 2015) with Marty McFly, both to change the past for the better and to undo the negative effects of time travel. One of the cars used in filming is currently on display at Universal Studios Hollywood.
