Had a couple co-workers (Sean and Josh) come up to lend a hand on the build. Finished all the extra side skin drilling into the aft section, added the 904-L straps and hung the firewall. Firewall is now drilled and I am working on the auxiliary forward section longerons and stiffeners. Adding the firewall really has it looking like it is coming together. (Things are busy outside of this build, so it may be a little slow going for a while)
