爱思英语编者按：对于泰坦尼克号中杰克死在冰冷的海水里这样的安排大家一致都有争议，因为长期以来的一个疑点是那块门板真的装不下两个人吗？前段时间导演卡梅伦出来讲空间够了只是浮力不够。现在美国著名电视频道Discovery做了实验证明只要Rose脱下她的救生衣绑在木板下面，就能产生足够的浮力救活两个人。导演最后只好说：“你们这些人搞清楚重点没？剧本让他死他就得死……”

Jack died for nothing! Experiment shows Di Caprio's Titanic character COULD have survived if he'd climbed onto Winslet's raft

TV show discovered that Jack, played by Di Caprio, could have survived the Titanic disaster if he had lifted himself onto the life raft

Wooden door would have supported both Rose and Jack if they had put her life jacket underneath

It is a debate that has raged since Titanic became one of the most successful films of all time: Did Rose leave Jack to die by not letting him up on the makeshift lifeboat as they floated in the ocean?

And now a U.S. television show has carried out a series of tests that show Leonardo DiCaprio's character could have survived the disaster had he lifted himself onto the raft from which Rose, played by Kate Winslet, was plucked.

The Discovery Channel's Mythbusters recreated the treacherous conditions after the Titanic sank in 1912 and, through hypothermia tests, discovered Jack would have survived the freezing conditions if he had climbed out.

Doomed: Jack, played by Leonardo Di Caprio, slips into the icy Atlantic waters as lover Rose DeWitt Bukater, played by Kate Winslet, clings on to a makeshift raft in the climax to blockbuster Titanic film

Going down: The closing scene from Titanic has now been reconstructed by U.S. show Mythbusters to see if it really would have ended in tragedy for character Jack in the film

Titanic director James Cameron told Mythbusters he believed the wooden life raft would not have supported both Jack and Rose. 

But the team found that if Rose had taken off her lifejacket and put it under the raft it would have given them enough buoyancy to keep both of them afloat. 

Reconstruction: Mythbusters, left, replicate the events from the blockbuster film Titanic, right

Happier ending?: The Mythbusters set out to see if Jack, played by Leonardo Di Caprio need not have sacrificed himself to save Kate Winslet's character, Rose

Discovery: The Mythbusters found that both Winslet and Di Caprio's characters could have fitted on the makeshift raft and survived the sinking

Hosts Adam Savage and Jamie Hyneman then carried out a hypothermia test to see what would happen if Di Caprio's character had indeed climbed out of the water and onto the wooden door.

A dummy with gelatin flesh and a water-heated copper cardiovascular system that was rigged to monitor body temperature was used to simulate Di Caprio’s character. 

The dummy’s body temp was set at 98.6° and  dressed in wet clothes. It was then set hovering above the freezing water in 29° F air as if he were lying on the wooden raft. 

The show found that as long as he was rescued before his body temperature dropped below 82° F, he could be revived. 

After an hour on the raft they found the dummy’s core body temp was 82.5° F meaning Jack would have lived had he got out of the water. 

Conclusions: Mythbusters Jamie Hyneman, left, and Adam Savage, centre, reveal their findings to Titanic director James Cameron, right,

In the film Rose was one of the last to be rescued. Historical documents show that Fifth Officer Harold Lowe, who was depicted rescuing Rose,looked for survivors 45 minutes. 

In a separate test the 'Mythbusters' team found that had Jack remained in the water for over an hour he would have died from hypothermia. 

Cameron, however, had the last word telling the TV show that Jack had to die as that’s what the script called for. 

He said: 'I think you guys are missing the point here.The script says Jack died. He has to die. So maybe we screwed up and the board should have been a little tiny bit smaller, but the dude's goin' down.'
