In the 1970s, Glendale, Burbank, and Pasadena created air support units that have been in place and highly successful for the past forty years. A couple years ago that the Glendale/Burbank Police Air Support Unit began a test program with the Pasadena Police Department, extending its reach to several other partner and contract cities. As aircraft technology and helicopter speed have increased over the past several decades, it has become possible to fly between the furthest apart cities, Burbank and Pasadena, in less than four minutes; however, it was not until recently that the cities decided to overlap and schedule their patrol flights to benefit these service delivery and public safety efficiencies.
