input: Challenger Deep

On 26 March 2012 (local time), Canadian film director James Cameron made a solo manned descent in the DSV Deepsea Challenger to the bottom of the Challenger Deep. At approximately 05:15 ChST on 26 March (19:15 UTC on 25 March), the descent began. At 07:52 ChST (21:52 UTC), Deepsea Challenger arrived at the bottom. The descent lasted 2 hours and 36 minutes and the recorded depth was 10,898.4 metres (35,756 ft) when Deepsea Challenger touched down. Cameron had planned to spend about six hours near the ocean floor exploring but decided to start the ascent to the surface after only 2 hours and 34 minutes. The time on the bottom was shortened because a hydraulic fluid leak in the lines controlling the manipulator arm obscured the visibility out the only viewing port. It also caused the loss of the submersible's starboard thrusters. At around 12:00 ChST (02:00 UTC on 26 March), the Deepsea Challenger website says the sub resurfaced after a 90-minute ascent, although Paul Allen's tweets indicate the ascent took only about 67 minutes. During a post-dive press conference Cameron said: ''I landed on a very soft, almost gelatinous flat plain. Once I got my bearings, I drove across it for quite a distance ... and finally worked my way up the slope.'' The whole time, Cameron said, he didn't see any fish, or any living creatures more than an inch (2.54 cm) long: ''The only free swimmers I saw were small amphipods''--shrimplike bottom-feeders.

input: Bill Russell NBA Finals Most Valuable Player Award

Since its inception, the award has been given to 31 different players. Michael Jordan is a record six-time award winner. Magic Johnson, Shaquille O'Neal, Tim Duncan and LeBron James won the award three times in their careers. Jordan and O'Neal are the only players to win the award in three consecutive seasons (Jordan accomplished the feat on two separate occasions). Johnson is the only rookie ever to win the award, as well as the youngest at 20 years old. Andre Iguodala is the only winner to have not started every game in the series. Jerry West, the first ever awardee, is the only person to win the award while being on the losing team in the NBA Finals. Willis Reed, Kareem Abdul-Jabbar, Larry Bird, Hakeem Olajuwon, Kobe Bryant, and Kevin Durant won the award twice. Olajuwon, Durant, Bryant, and James have won the award in two consecutive seasons. Abdul-Jabbar and James are the only players to win the award for two different teams. Olajuwon of Nigeria, who became a naturalized U.S. citizen in 1993, Tony Parker of France, and Dirk Nowitzki of Germany are the only international players to win the award. Duncan is an American citizen, but is considered an ''international'' player by the NBA because he was not born in one of the fifty states or Washington, D.C. Parker and Nowitzki are the only winners to have been trained totally outside the U.S.; Olajuwon played college basketball at Houston and Duncan at Wake Forest. Cedric Maxwell is the only Finals MVP winner eligible for the Hall of Fame who has not been voted in.

input: Wembley Stadium

Designed by Populous and Foster and Partners, the stadium is crowned by a 134-metre-high (440 ft) Wembley Arch which serves aesthetically as a landmark across London and structurally with the arch supporting over 75% of the entire roof load. The stadium was built by Australian firm Multiplex at a cost of 798 million (1.09 billion today). Contrary to popular belief, Wembley Stadium does not have a retractable roof which covers the playing surface. Two partially retractable roof structures over the east and west end of the stadium can be opened to allow sunlight and aid pitch growth.
