I was surprised to see the quote 'slip the bonds of earth' on a circular orbit. This seems pretty bound to earth. Wouldn't it have made more sense to include a parabolic escape trajectory? --[[User:Quantum7|Quantum7]] ([[User talk:Quantum7|talk]]) 10:01, 25 June 2018 (UTC)

:Except (as far as we know) Newton never considered parabolic trajectories. Whether he did or didn't, the original diagram didn't show anything beyond a circular orbit. [[User:Mr. I|Mr. I]] ([[User talk:Mr. I|talk]]) 12:36, 25 June 2018 (UTC)

Actually he's talking about ICBM's that have the potential to end civilisation in fire if actually launched, not the crash of a spaceship.141.101.107.156 04:39, 25 June 2018 (UTC) Agreed, the object emitted from the cannon is either a rocket or an ICBM. 172.69.158.46 04:51, 25 June 2018 (UTC)

Couldn't he be talking about the rocket being mistaken for whatever big bomb we use right now and start the whole mutually assured destruction gig? I hear that there have been a lot of close calls/radar malfunctions/whatever whatevers that almost sent us into the apocalypse. Come on, Didn't Germany write a song about that? (Granted, it's apparently the show of force that starts the war, but you guys get my point) 172.69.33.233 05:42, 25 June 2018 (UTC)

I am German and didn't write a song on that issue. The song that comes closest for me is Fylingdale Flyer by Jethro Tull.
