The descent of the bus-glider was pretty much the same as its starting sequence, just reversed.
First, the whole vehicle started to gradually decrease its speed bit by bit, all the way to the point where it came to a full stop. Then, the process reversed again, with the vehicle starting to gain speed again. This time, however, rather than moving forward, it was held by some sort of force that continued to slowly let it out of its grasp, all the way to the point where it entered a state of a free-fall.
In the end, the whole process reversed yet again, this time to properly kill the bus's downward momentum, grinding it to a complete halt right as the bus's wheels softly touched the ground.
Thud.
