UAV survey (poll) Question 1

Hello I am my first year of the surveying program at Penn College. As part of an assignment I need to do a "survey" of surveyors regarding UAVs. I will be posting a series of threads, each having a question with multiple answers. These being closed end questions, I hope I am covering most of the possible answers. The questions are less about the technical aspects of drone use and more about the decision to purchase, use and the results. I realize many of the answers are related, e.g., costs and efficiency. Thanks in advance to all respondents.
