At 9:45 P.M. CDT on 20 April 2010, during the final phases of drilling the exploratory well at Macondo,
a geyser of seawater erupted from the marine riser onto the rig, shooting 240 ft (73 m) into the air.
This was soon followed by the eruption of a slushy combination of drilling mud, methane gas, and water.
The gas component of the slushy material quickly transitioned into a fully gaseous state and then ignited into a series of explosions and then a firestorm.
An attempt was made to activate the blowout preventer, but it failed. The final defense to prevent an oil spill,
a device known as a blind shear ram, was activated but failed to plug the well.
At the time of the explosion, there were 126 crew on board; seven were employees of BP, 79 of Transocean,
there were also employees of various other companies involved in the operation of the rig, including Anadarko,
Halliburton and M-I SWACO. Eleven workers were presumed killed in the initial explosion. The rig was evacuated,
with injured workers airlifted to medical facilities. After approximately 36 hours, Deepwater Horizon sank on 22 April 2010.
The remains of the rig were located resting on the seafloor approximately 5,000 ft (1,500 m) deep at that location, and about 1,300 ft (400 m)
(quarter of a mile) northwest of the well

[Flight# AP101] Rescue Flight Mobile Regional to Deep Water Horizon and back to Mobile Regional.
(KMOB-Deep Water Horizon-KMOB) (Approx 2.5 hours)
-
Aircraft: Amphibian (However, if you wish to use a helicopter you may use this also, but only the helo platform at the rig will allow landing).
-
Weather: Your choice - but I would suggest clear.
-
Time: Nighttime (10:00pm to be exact).
-
Scenario:
You are with the US Coast Guard's Gulf Strike Team based at Mobile Regional Airport. It's 2200 Hrs. on April 20, 2010 and you have just received
an emergency request regarding the offshore oil rig, Deep Water Horizon. There are reports of multiple explosions at the drilling site located
approximately 117 miles due south of your base (186-deg bearing).
A rescue helicopter has also been sent to that location from a different base. The message came from the rig support vessel, Damon Bankston. The
Bankston has begun rescue operations and reports many oil rig workers in the water and still on the burning rig.
Take off from KMOB and find the burning rig. Land your amphibious aircraft in the waters alongside the burning rig and rescue the rig
workers. Then return to KMOB with the rescued workers. Take some pics to document the incident for your report (and the photo gallery)
MS Prinsendam, a Holland-America liner built at Shipyard de Merwede in the Netherlands in 1973, was 427 feet long
and typically carried about 350 passengers and 200 crew members. The liner was sailing through the Gulf of Alaska,
approximately 120 miles south of Yakutat, Alaska, at midnight on October 4, 1980, when a fire broke out in the engine room.
The vessel's master, Cornelis Dirk Wabeke (April 13, 1928 - August 16, 2011), declared the fire out of control one hour later
and the Prinsendam sent a radio call requesting immediate assistance. The United States Coast Guard at Communications Station Kodiak,
Alaska requested that the Prinsendam send out an SOS, but the captain declined. Chief Radio Officer Jack van der Zee sent one out
anyway about a half-hour later, which alerted nearby vessels.
United States Coast Guard, USAF Air Rescue Service, and Royal Canadian Air Force CH-113 helicopters which had greater range,
rescued the passengers and crew. Two USAF pararescuemen were inserted into one of the lifeboats. This boat was the last rescued
and was spotted only when the Air Force personnel signalled the on scene cutters. The cutters USCGC Boutwell (WHEC-719),
USCGC Mellon (WHEC-717), and USCGC Woodrush (WLB-407) responded in concert with other vessels in the area. The Sohio Intrepid and the
Williamsburg assisted on scene. The Williamsburg served a vital role as a communications platform and was the first vessel to arrive on
scene and take passengers on board. The Sohio Intrepid served as a platform for one of the USAF helicopters that was unable to refuel in flight.
The rescue took place during a period of steadily deteriorating weather. The passenger vessel capsized and sank a week later.
The rescue is particularly noteworthy because of the distance traveled by the rescuers, the coordination of independent organizations,
and the fact that all 520 passengers and crew were rescued without loss of life or serious injury.

[Flight# AP102] Rescue flight from Sitka (PASI) to sinking Prinsendam and back to Sitka.
(PASI-Prinsendam-PASI) (Approx 2.75 hours)
-
Aircraft:While the actual air rescue was flown by helicopters, we will fly amphibious aircraft.
-
Weather: Your choice - but I would suggest clear. Real weather was worsening.
-
Time: Dawn (daylight just arriving)
-
Scenario:
You are with the US Coast Guard based at Sitka, Alaska (PASI). It's early dawn and the morning light is just breaking. You receive information
that the cruise ship Prinsendam is burning out of control and they are abandoning ship and an SOS has been sent out. The SOS indicates the position of the
Prinsendam about 168 miles northwest of Sitka (heading of 263 degrees).
Take off from PASI and find the burning ship. Land your amphibious aircraft in the waters alongside and rescue the passengers from their lifeboats.
Then return to PASI with the shipwreck victims. Take some pics to document the incident for your report (and the photo gallery)
