Reply to comment by 7ECA in The Stratolaunch Roc, the largest aircraft ever flown, has just completed a 6-hour test flight. It aims to be a platform to launch reusable hypersonic craft from an altitude of 10 km by lughnasadh
Seems to me like the question is, "How can we get something up to enough speed and altitude that it can be picked up by a rotavator?"
