As a member of the Army's equivilent to the RAF's MCU, RCT Maritime
I had the privilage of visiting Gan on two occasions.
First was 71/72 time when Idi Amin was performing in Uganda spent three months on standby to assist with the withdrawal of brit nationals which never got activated. So we had three months of doing nothing got boring towards the end but we survived.
The second time was on a flight from Singapore to UK my then wife burst a ear drum after take of, on arrival at Gan the family were off loaded so she could get medical attention, we were put into transit accommodation and had use of the Blue Lagoon for meals ect, three weeks later we were on our way back to the UK low level in a Belfast. Long old journey following a great break in Gan fond memories.
