 With only wireshark, we can now extract only some pilot(s), keep only a time interval of traffic, or see some traffic properties.<br>
 With the help of tcpreplay/tcprewrite, we can sent the mp traffic back to a running FG session.
+==pilot individual file==
+In Wireshark, it is possible to extract each pilot flight individually, the filter to use looks like:
+ frame contains "callsign"
+and to exclude a pilot:
+ !frame contains "callsign"
+This way you can have each pilot flight separated, and if needed, you can merge again 2 or more pilots in a file, eg you have recorded a diamond formation, and you want to practice the left wingman position, either you remove the existing one for the .cap, or you merge the 3 others again, after having done individual .cap.<br>
+Wireshark come with mergecap, to merge multiple .cap file, and taking care the chronological order is respected.<br>
+The provided editcap can be used too, if you need to add a time offset to a plane, to address latency recorded issue.
+It's sometimes difficult to have lot of matching shedules, when you are training in an aerobatic team, and we have here a good way to train with other mp pilots without being connected. You can even practice by file exchange, the leader make a flight, send the .cap to the second, wich add his flight, then pass to the 3 etc...
