Hi Grapple,
My dad went out in '58 for Operation Grapple, he was in the RAF based on the Island. He witnessed 2 A bomb and 3 H bomb tests. he died in '98 aged 60 yrs.
I have his Kitbag, it has a painting of the Frigate bird with an anchor as it's claws and Grapple underneath.
The Palms of his hands were pressed deep into his eye sockets and he had his back to the blast and he saw an xray of his hands.
A top secret document now released stated that they were to test the effects of the bombs on machinary and personel.
Regards,
Rewcastle.
