why no track log?

So let me try this again. Any idea why no track log can be found for this not blocked flight. The map shows the correct routing. It is a privately owned aircraft by N20TL LLC. flightaware.com/live/flight/N20TL

I noticed that the same error occured for the same aircraft (N20TL) on an IFR flight on 7 Dec 2006.

It’s a bug in our code when there is too much time between the departure message and first position message.

That often occurs when an IFR flight departs, after getting a clearance on the ground, in a non radar area and/or picks up the clearance in flight.
