What the hellSpoilerDamn it I just want to explode the rocket, why do I have to get the fuel and starter and sugarbomb just to make it explode. On a side note sugar bombs are scary, superjet in fallout 3, dangerous reactant in new vegas. I am never buying corn pops again.
I don't think you need the items. . .Spoilerif you have a certain science requirement (not entirely sure since it doesn't list one next to the option)? I just happened to have three sugar bombs on me (chalk one up to experience with Fallout 3), but after I gave them to him I went to the launch deck and it gives you an option to make them crash into each other anyways. I didn't opt for that and just left it alone, since I'd assume there was a karma penalty and they were set to blow anyhow.
It's totally worth it seeing them explode, though. Not quite as epic as nuking Megaton, but definitely up there.
I didn't even know there was an option to blow them up, I only saw the option to make them crash into each other. I just let them go.
