Re: Ray's TAS shuttlecraft...
I appreciate your desire to adhere, at least overall, to the TAS "designs", but the more I look at the "heavy lander" the more I think of how TAS deviated from Matt Jefferies' design sensibilities and how those designs blended so well with the ideals represented in TOS. The somewhat boxier shape of the Class F standard shuttlecraft does carry an important advantage: it seems to allow for an interior that would be much more space-efficient. The Class L is much curvier, even more so than most TNG designs I recall. This strongly suggests to me that it would be less useful for hauling personnel and cargo. Just my two credits' worth...
