with all the turbulance they would have encountered crossing over the various terrains i think an anti-tipping device would be prohibitive. the v-1 would be jostled enough to possibly detonate it. may father told me several stories of V-1s and 2s. his base was on "buzzbomb alley"...one of the main routes they took to their inland targets. one of them did explode a mile from their base and they could feel the rumble. yep, when the engine quit they entered a very steep glide path down....so as long as you heard the engine pass over you, you were ok. he told me about spits "tipping" them and that they dove down to match the V-1s speed and just lifted the wing enough to sail it back in a wide arc to the north sea. they were fairly low on fuel by that time anyways. he also told of when they were escorting the bomber groups they would see them being launched ahead of them. he surmised the germans were afraid that the launch site may be bombed so they shot off the ordnance they could.
