Question APRS Hacked? Spoofed?

So, after being alerted by a fellow flyer, either my plane has been stolen (airport gets locked after 11pm, this shows the plane was airborne at midnight) or my tracker is being spoofed! I am confident the plane is tucked away in the hangar, but the APRS tracker says otherwise.

The track is identical to the one I actually flew on Friday:
http://aprs.fi/#!mt=roadmap&z=13&ts=...call=a%2FN792F

Saturday, a random ping showed up (I've seen this happen before) based on one of the packets from Friday over the Chesapeake:
http://aprs.fi/#!mt=roadmap&z=6&ts=1...call=a%2FN792F

And now today, I have a mysterious track identical to Friday's starting at Midnight and ending at ~4am:
http://aprs.fi/#!mt=roadmap&z=9&ts=1...call=a%2FN792F

Any ideas? Is there some April foolery going on? If so, good one.

Andy,

Are those APRS track positions valid? If that's the case, I've seen that happen occasionally on aprs.fi. I would have expected that the website would assemble tracks based on the time sent by your beacon, but it sometimes seems that it uses the time of arrival of your information from the network.

I'm sure there's an APRS expert on VAF that can give you a more correct answer.

There appears to be a bug somewhere in the system. As evidence, it would seam Vlad started a repeat trip to Sun-n-Fun on Monday afternoon - the same track as three days earlier. He too has a separate, single beacon in the middle of the night.

Default Since it's Vlad

... it could just be he's out night-flying, trying to penetrate airspace undetected. Standard MO, right?
