Hey there, I'm new to this forum. I'm part of a group of engineering students exploring the possibilities of launching small rockets to place microsatellites into orbit, off of a modified Learjet. Are there a lot of pilots on this site, who might be able to help us get an idea of the performance and flightpath necessary to achieve that? Any help would be appreciated. To start, we're trying to find the maximum safe upward climb angle, top speed and top altitude which could be managed concurrently to launch the load. ~Siegfried
