At least they weren’t involved in the infamous Reddenbacher Incident.

A large hyperbaric chamber was built to test the mental performance of personnel under high atmospheric pressure. O-5s and O-6s were performing mentally taxing tasks as the chamber’s pressure was slowly increased to the equivalent of a depth of 600 feet. Unfortunately, the contractor wasn’t told the rank of the people who would be using the chamber, so it was built to the standards of equipment intended for use by lower enlisted.

The door latch failed, the door flew open, and the chamber underwent explosive decompression. Almost every Colonel popped.
