The big thing missing in Prestwick's portfolio is training. To give some idea of the size of the hole, in 1990 - when Prestwick's last major crisis kicked off - 84% of the airport's total aircraft movements were in the 'test and training' category. Then BAe Flight Training moved to Spain and the export of the UK's massive training industry began. Weather was a factor, for sure, but unfortunately we've priced and regulated our pilot training industry out of existence.
