1504 Hrs Local: 2 CH-47's heading to Tioga Marine Terminal. One about to land and another just off Ft. Indiantown looks like it is inbound as well.
Not sure which frequencies they would be on so not monitoring. I am just off of their flight path in Philadelphia if anyone has the correct frequencies.
You can hear them using LiveATC streams for KABE and KPNE. For PNE, use the one that includes tower and Philly approach. When I was listening, you'd hear takeoff/departure/handoff on the ABE feed and then the rest of the transit to Tioga on the PNE feed.
