Today I riveted the newly fabricated F-710B & F-711D horizontal stabilizer attach angles to their respective bulkhead. For access I unclecoed the aft top skin and F-709 bulkhead (these were installed just for shipping, so they had to come off anyway). Access was a bit limited for some of the outboard rivets, and I had to use straight and offset sets, and no retainer spring on the gun for them. Now it's time for a little FORWARD progress!
