No candidate airport is ALIGNED (Δhdg ≤ 25°) with the current track of 141°, so the plane is likely still turning after departure from KPNE or KHPN. The recent flight history shows frequent hops between KPNE, KHPN, and KLOM in the Philadelphia/New York metro area, and the current position (39.78, -74.58) is just southeast of KPNE at low altitude (4275 ft) and moderate speed (295 kt), consistent with a climb-out from that area. Given the past prediction pattern where I incorrectly guessed KIAD instead of KHPN, I bias toward KHPN as the most common recent destination, though the geometry is ambiguous.
