Please answer the following question: Write a multi-choice question for the following article, with the given choices and answer: Article: International teams have spent nearly half a year looking for evidence of the missing Malaysian Airlines plane, a search that includes the hunt for the aircraft's so-called black box, which holds flight data that would likely explain what caused MH370 to move away from its course. But many aviation experts wonder why, in our increasingly networked world, divers are searching the Indian Ocean for a metal box when technology already exists that would enable planes to stream black box data to the ground in the event of an emergency. Black boxes have been on planes since the late 1950s, and now every commercial aircraft has two: a flight data recorder and a voice recorder. (Although they are referred to as black boxes, they are typically orange in color, making them easier to spot in waters.) Black box recorders are mainly used to investigate the cause of in-flight accidents. While black boxes are built to survive a crash and long-term submersion in water, it can be a real challenge to find the device if a plane has gone down in the ocean. While each box contains a beacon , the unit only has enough battery power to transmit a signal for 30 days. After the crash of Air France Flight 447 in the Atlantic Ocean in June 2009, it took divers two years to find the black box. Pierre Jeanniot, a Canadian engineer who helped perfect black box technology about 40 years ago, feels that the device, in its current form, is " _ ". He started to question its effectiveness more than a decade ago, after seeing the broken pieces of the black boxes in the 2001 attacks on the World Trade towers in New York. Jeanniot is now on the advisory board of a Toronto-based firm that has built a live-streamed black box system. When a plane experiences an irregular event, the system can send streaming data off the aircraft to one of the satellites and then down to ground-based servers, where the message is interpreted and sent to the airline. It seems necessary that the loss of MH370 and other similar cases wake more people up to the fact that... Options: A They approve of the system since it may save time, money and effort. B They consider using the system as the bottom line of costs. C They are reluctant to start the system because it still needs improving. D They are unwilling to equip planes with the system as it cuts their profits. Answer: D They are unwilling to equip planes with the system as it cuts their profits. Question:
A:
What's airlines' attitude towards the live-streamed black box system?
