After flying a bit farther, we were able to see both B15a (on the left) and B15j (on the right). As you can see, the walls of both icebergs are almost perfectly vertical. I took this shot on the 18th of October after the iceberg cracked on the 8th or 9th. We were the first people to see the new fracture close up (the intercontinental plane pilots could have seen it if they were looking from about 50 miles away). The walls of the two icebergs match up perfectly and the sea ice between the icebergs also fractured cleanly. The dark zig zag in the center of the image looks like open water, but it is in fact covered by a thin layer of sea ice.
