Donald R. Bensen’s 1978’s And Having Writ… is a stand-alone comedic alternate history novel.
Due to mechanical failure during re-entry, first contact between humanity and the crew of the starship Wandererseems certain to come in the form of a high-velocity impact near the location known to humans as Tunguska. This catastrophe is avoided, thanks to skillful piloting and cutting-edge tech. The Wanderer is able to divert and set down in the Pacific.
On board: Captain Dark, Recorder Raf, Metahistorian Ari, and Integrator Valmis.
Explorers have been given strict non-contact guidelines, but these do not take into account being marooned on alien worlds. The guidelines particularly do not cover this particular case: primitive locals, having retrieved the extraterrestrials crewing it, accidentally sink the starship in the Pacific.
If Dark, Raf, Ari, and Valmis are to get home, they will need to use local resources to do so. Local resources are, alas, currently insufficient.
