2-MAPP has been confirmed as NOT spoopy. This is a photo mapping aircraft. Check out Planefagging 101.
2-#### planes showing up only on civilian ADSB are probably legit. The ones we are particularly interested in are the ones playing hard to get and popping up on ADSB Military.
Civilian planes should not show on ADSB Mil unless they are working for the military (see Cobham & ATAC in PF 101).
