Evacuation of civilians from the Channel Islands in 1940 one suitcase. The Lieutenant Governor of Jersey and Lieutenant Governor of Guernsey left their islands on board ships on 21 June 1940, the day France surrendered. Ships urgently needed to evacuate soldiers from France in Operation Ariel, were diverted to help civilians in the Channel Islands.

Requisitioned in 1939 as a troopship, she transported 1,800 schoolchildren from
SIMMON virtual machine for testing of a single guest program running there. CP-40 supported many virtual machines for time-sharing production work. CP-40 evolved by many stages into the present VM/CMS operating system. SIMMON was a useful test vehicle for many years. SIMMON was designed to dynamically include independently developed programs (test tools) for testing the target guest program. The SIMMON kernel maintained control over the hardware (and the guest) and coordinated invocation of the test tools. Two modes of operation were provided: In this mode, each instruction in the guest program was simulated without ever passing control directly to the guest.
