I suspect that the weapons rack can include a CAD type thing that pushes the munition down before the rocket engine fires.
On the pushing down this is hard successfully for an aircraft that lives nap of earth.
As to storage of the missiles in the cabin I recommend Holland's "Big Week" about the bombing campaign in Europe (one of, if not the best on the subject). It includes numerous examples on how bombers just vanishing after their load explodes and how devastated the other crews were witnessing it. Sure fortified their belief they would not make it to their going home mission count. Not exactly a moral builder.
