Missing Malaysia Flight 370, was It hijacked ?

30 December 1966, the United States and the UK executed an agreement through an Exchange of Notes which permit the United States to use the BIOT for defense purposes for 50 years (through December 2016), followed by a 20-year optional extension (to 2036) to which both parties must agree by December 2014.[19] No monetary payment was made from the United States to the UK as part of this agreement or any subsequent amendment. Rather, the United Kingdom received a US$14 million discount from the United States on the acquisition of submarine-launched ballistic missile system Polaris missiles per a now-declassified addendum to the 1966 agreement.

On 1 October 1977, Naval Support Facility, Diego Garcia, was established as the senior United States Navy command on the island. At the time the NAVCOMMSTA was the primary tenant, but as the new major facilities were completed, most notably the expanded anchorage and mooring area and the extended airfield, other tenants were commissioned.[27]

In 1980, the United States Navy established the Near-Term Prepositioned Force of 16 ships. Then NTPF became the Afloat Prepositioning Force (AFP) and eventually Maritime Prepositioning ship Squadron Two (MPSRON 2) consisting of 20 deep-water pre-positioned logistics ships anchored in the lagoon.[28]
In 1981, the Naval Air Facility was commissioned. It was decommissioned in 1987 and its responsibilities returned to the NSF.[27]
In 1982, Construction activities were transferred from the Seabees to a consortium of civilian contractors, and the majority of the projects were completed by 1988.[26] On 26 March 1982, Barbara Shuping and five other women were assigned to the NSF. Prior to this assignment, no women had lived on island since those on the plantation in 1971.[29]

In 1985, the new port facilities were completed, and the USS Saratoga (CV-60) was the first aircraft carrier to tie up.[30]
Strategic Air Command began deploying Boeing B-52 Stratofortress bombers and aerial refueling aircraft to the newly completed airfield facilities in 1987.[31]
Following the Iraqi invasion of Kuwait in August 1990, three ships of COMPSRON 2 sortied, delivering a Marine Expeditionary Brigade to Saudi Arabia for participation in the Gulf War. Other COMPSRON 2 ships offloaded the munitions, bombs, and fuel on Diego Garcia that were required for the American bomber fleet that deployed to airfield.

IN light of the recent events surrounding the ill-fated MH370 flight that disappeared from radar detection in the early hours of March 8, numerous geographic locations have come to light, and one in particular that has become a point of interest among investigators and ordinary folk is a little-known spot in the middle of the Indian Ocean called Diego Garcia.

The atoll, which takes the form of a ring shaped reef, first came to world attention in 2004 after the Asian tsunami disaster and now has resurfaced thanks to conspiracy theories that have sprung up connecting MH370 to it.

Because of its favourable ocean topography, including a deep underwater trench, the island was shielded from major damage during the 2004 tsunami. While a 1.8m-high wave did hit the island, the underwater canyon essentially bore the brunt of the assault and there was no major impact on the island's facilities or its people.
