[Battlestar Galactica] What tactical advantage do the launch tubes have over simply launching from the landing bay?

It confers some velocity to launched vipers, but unless the battlestar is broadside to the target that velocity is largely wasted and sometimes even detrimental.  
Why not simply fly out the front side of the flight pod and make your turn towards target or destination while still at low speed when it's easier to accomplish?

if you open the main pod doors you have to wait until the very last pilot is in his viper and all the knuckle-draggers are safely away, else they'd all be exposed to the vacuum.  With the launch tubes you can launch as needed or in waves.
