Wow, thank you. There is a way to look up flights but I don't know how. But using one of your links, https://uk.flightaware.com/ , I was able to click the drop down menu and paste in tail #'s for some of Epstein's aircraft - until I reached my limit of searches apparently.      It's not much, but provided a few locations: Tail No. | State | Aircraft Year | Make/Model | Route in Year | Owner  |  Link:  N423TT	|  New York	 |  1988 | Gulfstream Aerospace Gulfstream IV (twin-jet) (GLF4)  | West Palm Beach, Florida to Jacksonville, Florida – 2013 |  JEGE LLC  |  http://archive.is/52Mse     N331JE	| 2001 Bell 430 (twin-turboshaft) (B430) helicopter  |  San Juan, Puerto Rico to Charlotte Amalie, Virgin Islands – 2016 |  HYPERION AIR LLC  |   http://archive.is/qC24Q     N491GM	| New Mexico |	1999 |	Helo (helicopter) |   Warrenton, Virginia to  Wilmington, Delaware --  2012   |  FREEDOM AIR INTERNATIONAL INC  |        http://archive.is/a5QeY      N909JE	  |  Florida	|  1974 |   "N909JE - STARBRIDGE LANDING INC (DOVER DE) This aircraft (N909JE) is not available for public tracking per request from the owner/operator."     N908JE	 | Virgin Islands | 	1968 | Boeing 727-100 (tri-jet) (B721) | West Palm Beach, Florida to Brunswick, Georgia – 2016  |   JEGE INC  |    http://archive.is/FvgPO     I couldn't get information on these: 2583TC	Virgin Islands	1968	 2907TC	Virgin Islands	2008	 0730TC	Virgin Islands	2006 4105TC	Virgin Islands	2007	 3499TC	Virgin Islands	2010	 2908TC	Virgin Islands	2006 2709TB	Virgin Islands	1999	    EDIT to add: Here is a recent flight of another plane, or of the 1988 Gulfstream with its tail number changed:  N120JE  |  1988  |  Gulfstream Aerospace Gulfstream IV (twin-jet) (GLF4)  |   Paris, France to Teterboro, New Jersey --  March 13, 2018  |  	JEGE LLC   |   http://archive.is/lX2vz   credit to @new4now
