It was not an airplane, and thus could not take off.
no it cannot take off if it is going slow
It all depends on how much power is in the engines that can enable an airplane to take off at a steeper or shallower angle. Airplanes used for air shows and fighter jets are able to take off at a steep angle. Bush planes can also take off at a steep angle. A heavily loaded Air Bus, on the other hand, needs more clearance to be able to take to the air and thus may take off at a more shallower angle than a typical CF-18 Hornet would!
you take it off the shaft
Usually about a minute.
each plane has a set take off speed , flap position and weight for take off
to gain speed for take off
Depends on the size and type of the airplane. I wonder that it takes about four minutes for a Boeing 747-8.
Usually about 45 minutes or closer to an hour :) Improved: There are factors that alter the answer due to a) weight of airplane, b) size of airplane, and c) current weather conditions affecting take-off.
About 160 Knots
It then produces lift due to wing configuration and can take off
