I"m reading the nbr 35 of Espace Magazine where there's an interview of Tahir Rahman (who posted here several times).
Apparently, Buzz almost forgot to unload his left arm pocket which contained a silicone disc with all kinds of messages from 73 countries. He threw it from the ladder and Neil kicked the bag slightly away......But I'm afraid the blast from liftoff must have kicked it even further away or destroyed it!
Here are the 73 countries I wonder if it's correct??
