This is another version of bell’s spaceship paradox. Consider two spaceships A & A’ separated by a distance L, and are tied by a non elastic thread. They are on earth. This time the two spaceships are not moving instead I'm moving. I’m in a distant planet and i starts to accelerate and reach at 99% speed of c and stops accelerating, now from my point of view the two spaceships are moving towards me at 99%speed of c. So they must undergo length contraction, therefore the A’ ship must increase its distance from A because of length contraction and the thread must break. But it won't break in reality, So you will answer the thread won't break, then what about length contraction, won't it happen here?
