With the right backdrop and scripts, programming a sprite to "fly" may be fairly simple, but adding gravity helps with making platformers as well as jetpack games. The following script can help with the gravity implementation in a flying engine:[factually inaccurate?] 

when green flag clicked
forever
  if <key [space v] pressed?> then//You're flying
    glide (0.4) secs to: x: (x position) y: ((y position) + (40))
  else//You're falling
    glide (0.4) secs to: x: (x position) y: (-110)

Or you can simply use Velocity: 

when green flag clicked
forever
  if <key [space v] pressed?> then
    change [Y Velocity v] by (0.1)
  else
    if <(Y Velocity) > (-8)>//Maximum falling speed
      change [Y Velocity v] by (-0.1)//Gravity
    end
    if <touching [ground v]?> then //A ground sprite
      set [Y Velocity v] to (0)
    end
  end
  change y by (Y Velocity)
