As many know (i.e. I am revealing no secrets), you can see the tail-section from the summit of No. Brother, esp. when the sun is right and glinting from it.
The 'whack from the Fort summit is not long and there is a faint herd-path, but if you lose it, as I did returning to the Fort summit on a solo hike, you'll find yourself in wall-to-wall spruce - the slowest, most miserable variety of hiking. I too found the wreckage somber.
I agree that this is not a good hike to do solo and I did nearly step in some crevices in rock jumbles when I also lost the herd path between Fort and No. Brother. (Better lucky than smart, sometimes.)
