Yes, as long it is not on during takeoff.
Every aircraft have their own procedure . mostly in airlines when u r in takeoff run u will calculate v speeds and depends on that the procedure will vary . for example you got one engine failure during takeoff run and its before V1 speed you can abort the takeoff and if you already crossed V1 speed you must takeoff and then you can follow the A/C engine failure procedure to land back asap using single engine.

The flaps help to increase lift, which is essential to the landing and takeoff phase[s].
None of the spacecraft exploded during takeoff. Apollo 13 had an explosion while in the translunar coast phase of their mission, but that was more than a day after takeoff.
Safety belts during takeoff and landing and while en route; shoulder harnesses during takeoff and landing.
V2 is the actual speed at 35 ft above the runway as demonstrated in flight during takeoff with one engine inoperative. a.k.a. - takeoff safety speed.
You might get receive an order to "Hold short of runway" before takeoff, but not during takeoff. That just means that the tower wants you to remain on the taxiway because another aircraft is taking off or landing and hasn't yet cleared the runway. Once you're "cleared for takeoff" you can taxi onto the runway and takeoff
