I track N908JB and it’s last flight 1/15 from KJWN to KEYW suddenly has an extension in the map heading back into his home port KPBI (I would imagine from the looks of the radar track). Is this a glitch or could they have flown VFR in the falcon? 
You can see the final VFR segment at 17500ft in the tracklog (the last dozen rows or so after the descent into EYW).
Thanks for the quick response Mark. I’ll make sure to check the track logs first from now on when I spot one of these “glitches”.
Wow, talk about quick cancellatiojn of IFR descending out of Class A airspace 
It was actually two flights, seperated by a bit of time on the ground.
Descent into Key West:
03:51PM 2616N/8217W 542 39000
03:54PM 2551N/8209W 528 34300 descending
03:55PM 2542N/8207W 538 29500 descending
03:56PM 2533N/8204W 550 25400 descending
03:57PM 2525N/8202W 531 21300 descending
03:58PM 2517N/8200W 519 18000 descending
03:59PM 2509N/8158W 505 14600 descending
04:00PM 2502N/8156W 473 11000 descending
04:02PM 2451N/8153W 364 8300 descending
04:03PM 2446N/8152W 317 5600 descending
04:04PM 2442N/8151W 294 3400 descending
04:05PM 2437N/8151W 283 2100 descending
04:06PM 2433N/8150W 263 1600 descending
04:07PM 2433N/8148W 151 700 descending
And then after about 20 minutes on the ground, they took off VFR from Key West and picked up flight following after climbing to 17500 feet:
04:42PM 2534N/8056W 453 17500 climbing
04:44PM 2543N/8048W 454 17400 descending
04:45PM 2548N/8043W 450 17500 climbing
04:46PM 2555N/8040W 444 17400 descending
04:47PM 2602N/8036W 439 15900 descending
04:48PM 2608N/8032W 418 13800 descending
04:49PM 2618N/8026W 338 10000 descending
04:53PM 2635N/8016W 258 2500 descending
04:57PM 2641N/8009W 129 600 descending
