Question: What is the scheduled local departure time and the actual departure time of the flight from Philadelphia to Harrisburg with the plane's tail number N627AE on the 13th of August 2018?
Evidence: scheduled local departure time refers to CRS_DEP_TIME; actual departure time refers to DEP_TIME; from Philadelphia refers to ORIGIN = 'PHL'; to Harrisburg refers to DEST = 'MDT'; tail number refers to TAIL_NUM; TAIL_NUM = 'N627AE'; on the 13th of August 2018 refers to FL_DATE = '2018/8/13';

SQL:
SELECT CRS_DEP_TIME, DEP_TIME FROM Airlines WHERE ORIGIN = 'PHL' AND DEST = 'MDT' AND TAIL_NUM = 'N627AE' AND FL_DATE = '2018/8/13'
