The devices gained notoriety due to the Challenger disaster. After the recovery of the vehicle cockpit, it was discovered that three of the crew PEAPs were activated: those of mission specialist Ellison Onizuka, mission specialist Judith Resnik, and pilot Michael J. Smith. The location of Smith's activation switch, on the back of his seat, means that either Resnik or Onizuka could have activated it for him. This is the most conclusive piece of evidence available from the disaster that shows that at least two of the crew members (Onizuka and Resnik) were alive after the cockpit separated from the vehicle. However, if the cabin had lost pressure, the packs alone would not have sustained the crew during the two-minute descent.

The partial-pressure launch-entry suits replaced the PEAPs, which were subsequently followed by the "ACES" full-pressure suits, which include self-contained oxygen tanks.
