At its face it does sound pretty crazy but I found some analogs of previous and ongoing projects that provide some reason to suspend disbelief.

Here's what I can find on high G launch vehicle's and payloads:

Breakthrough Starshot: Backed by physicist and VC Yuri Milner and lead by former director of NASA Ames, Peter Worden. 10,000 G's. Project Ongoing. [1]

Hiller Hornet: US Army helicopter, powered by jet turbines located at the tips of the helicopter blades. The turbines operated under 14,000 Gs. Project Completed [2]

HARP Project: Joint US Army & Canadian effort. Successfully launched electronics (radios, control systems, etc) and solid fueled rockets. 10,000+ Shock G's. Project Completed. [3]

A variety of documents come up while researching g-hardening electronics. The US Army Research Lab a a few papers. Linked one of them. 30,000 + Shock G's. Various Projects Completed and Ongoing[4]

The Hiller Hornet is likely the most applicable given it is a propulsion system operating at over 10,000 G's. I wonder how they designed the Hornet's turbine given Finite Element Analysis wasn't really a thing in 1950.
