It's too heavy.
And even if they were to manufacture it, the impact of the crash would kill everyone anyway. so wouldn't be of much use.
Also, whoever gave this answer clearly hadn't read the categorization.
The flight recorder (black box) is made mostly out of Titanium. If one built an airplane out of Titanium it would be too expensive and would never be able to get off the ground.
AnswerThe SR-71 was made mostly out of Titanium (very high strength to weight ratio) and it got off the ground fine. It was also a two-seat airplane that cost $33 million in 1960s dollars, so no one would ever be able to afford an airliner made out of it.Answer
I don't know if it is true that black box is made of Titanium, or if the SR-71 was made (partially at least) from Titanium. But I know that black box is VERY compact, meaning it is very rigid and heavy relatively to its size. On the other hand SR-71, even if it is made of Titanium, could be easily destroyed if it had crashed to the ground. And the reason is because it is not so compact, it is not so rigid. It is an airplane and it should be light relatively to its size.
So the answer is, that material is not the ONLY reason why the black box is not damaged. It is the way that black box is constructed, compact and rigid. That makes it heavy relatively to its size. And that is why, this design can not be applied to the airplanes.
Answer
Sometimes the 'black box' is not even found, much less completely protected during a crash. The data recorder is designed to withstand certain abuse that even if the aircraft could survive it, the human bodies inside could not.
As for the use of titanium, it is a very misunderstood material. It is not as strong as steel, and certainly isn't 'indestructible'. Titanium's advantage is a relatively high strength-to-weight ratio, which is why it is used for aerospace applications, where a combination of light weight and high strength are important.
The SR-71 was made with titanium skin to withstand the heat created by air friction at Mach-3+.

Why did The World Trade Center collapse?
Al Qaeda terrorists, masterminded by Osama bin Laden, are responsible for the tragedy. Two commercial jets filled with 10,000 gallons of jet fuel crashed into the World Trade Center towers, cutting off all the elevators and severely damaging the structure of the building.
The fire alone couldn't have melted steel, but the fire with the pressure from above, bent the support structure that was damaged by the jet. Once one floor collapsed, the rest followed.
