I love the idea of building a rocket in VR. As if your a kid sitting in front of an ultimate rocket kit picking parts that snap together. Holding the main part with one part and grabbing attachments and placeing with the other hand. Being able to instinctivly look at your model in you hand. Then placing it on the launch platform and slamming a big red button that starts the ignition sequence.
Running system checks in the cockpit. All system nominal!
