MH370 may have been brought down by 'rogue' pilot: air crash expert
Flight officer Rayan Gharazeddine looks out of a Royal Australian Air Force (RAAF) AP-3C Orion as it flies over the southern Indian Ocean during the search for missing Malaysian Airlines flight MH370 March 22, 2014.
CANBERRA -- A leading air crash expert has said missing Malaysia Airlines fight MH370 was likely to have been in controlled flight as it hit the water, giving life to the theory it was brought down by a rogue pilot or hijacker.
Air crash expert Larry Vance told Australia's Nine Network that there was no other way to explain why the flaperon, found off the coast of Madagascar, was "extended" meaning it would have been in controlled flight as it hit the water.
Vance said the only way to extend the flaperon, something which happens when a plane is attempting a landing, was for the pilot to engage a switch, something which is unlikely to have occurred during an sudden disaster.
"You cannot get the flaperon to extend any other way than if somebody extended it," Vance told the Nine Network's 60 Minutes program overnight.
"Somebody would have to select it (in the cockpit)."
Vance said, from photos released of the flaperon, there was evidence to show the aeroplane hit the water at a controlled speed, pointing to it being a "human engineered event."
"Somebody was flying the aeroplane into the water... There is no other alternate theory that you can follow of all the potentials that might have happened. There's no other theory that fits," he said.
"The force of the water is really the only thing that could make that jagged edge that we see (on the flaperon). It wasn't broken off. If it was broken off, it would be a clean break."
Meanwhile, Australian Transport Safety Bureau (ATSB) crash investigator Peter Foley said there was a possibility that someone was in control of the plane as it went down.
"There is a possibility there was someone in control at the end and we're actively looking for evidence to support that," he said on Sunday night.
He admitted that if it was brought down by a "rogue" pilot, the wreckage could be outside the parameters of the Australian-led 120,000 square kilometer search zone. The search for the Boeing 777 is scheduled to end in coming weeks, considering less than 10,000 square kilometers is yet to be searched.
"If you guided the plane or indeed control-ditched the plane, it has an extended range, potentially," Foley said.
MH370 was a scheduled passenger flight bound for Beijing from Kuala Lumpur. There were 239 passengers and crew on board.

Students finish answering the questions and then share their answers.
Step 3 Choose the right modal verbs. (3mins)
Guide students to understand in which situation should “must, can’t, could, might” be used through exercise. “Must” should be used when you are very sure something is true. “Can’t” should be used when you are sure something is not true. While “could” and “might” are used to show that people are not sure about something.
Let students finish the modal verbs choosing exercise in 4a.
Step 4 “Who is best at deducing” Game（2mins）
Based on the pictures given, students fill in the blanks in 4b and stand up to say out the correct modal verbs as fast as possible

Step 6 Summary and learn(3mins)
Ask students to look at the sentences in different tenses and try to conclude the structure:
①Simple present tense:
Modal verbs + V原
②present progressive tense
Modal verbs + be + Ving
③present prefect tense
Modal verbs + have + V过分
Step 7 Detective Game(4mins)
Let students choose one detective from six detectives and play the game by answering questions related to modal verbs in different tenses to make inferences.
Students choose one picture and play the game by answering questions.

Step 9 Observe and learn (2 mins)
Ask students to observe the general question sentences with “can” and find out the structure of general questions.

Get students to work in pairs to make conversations by using general questions starting with “can” to talk about the unknown objects on the desk in front of the class. The teacher gives a model first.
2. While some students are delivering the conversation, let other students listen carefully.
3. Some pairs act out their conversations, the rest of the students listen to the conversation given by peer and answer questions from the teacher.
Step 11 Group Work（6mins）
There are 7 clues to find out the suspect X.
Because of finishing the above tasks, each group will get a clue about the suspect X’s gender, eyes, mouth, nose, ears, hair and glasses. But each group only owns a clue. So each group should find out all clues by asking other groups questions and draw the portrait of suspect X. The group that finishes the task within the shortest time is the winner.
Six students are as a group.
Three students in each group go to other groups to get all clues by using the general questions with inferential modal verbs to make inferences. And the other three students stay in the group to answer questions from other groups.
After the clue-searching procedure, the group work together to finish the information card and the portrait of the suspect X.
