WHAT TOOK YOU SO LONG? Boeing finally has it’s Delta 4 stacked for testing. Weren’t they supposed to launch their EELV first…? Hmm.
So, these things finally get off the ground this year, but when will we see the vaunted modularity of the systems come into play? I for one would like to see the triple-tandem heavy lift version lift off. It’s no Saturn V, no, but it’d be something to see.
