Jim....ye be right re Goddard workin on liquid fuel rockets. However, he did a lot of work, from patent to working models for the Army, on solid fuel stuff. Morters, recoiless rifles and heavier stuff.
If you are plannin on bein shut in for a week or so, check out the three vollume set titled "The Goddard Papers" Govt printing office did em years ago. Bout 3,000 pages of his patents, contracts, letters etc. Hell of a good read. He even made big vacuum tubes, turn of last century, for measuring recoil of free gun in space. Offshoot of this was functioning radio and TV tubes made by (I think) Collins.
