In early December, just as I was starting to get into ship spotting, I saw a couple of vessels headed up river towards Philly. One of them, the Cielo di Iyo met with the harbor pilot right as I had my drone up. I was able to capture the Pilot coming to meet the vessel and CLIMBING the ladder to get on board just before she passed beneath the Walt Whitman Bridge.
