I was on of the original 73 (Christmas Island)  Sqd wh were sent to malden to prepare the sites for the AWRE personal, from living accommadation to the instrument sites.  We arrived in April 57, and were there for the first 3 Bombs that were dropped, all the following bombs were dropped on Christmas Is. after I left for UK. I still have the copy of the news sheet printed on the 15th May, which stated that it was the only paper to print the news of the first drop on the day it happeded.
