This is a rather unorthodox concept I stumbled upon. It was know a plane could fly with more weight than it could take off with so hence this system. The idea was the Maia would have a huge amount of fuel onboard to cruise to the various far flung reaches of empire. The smaller Mercury would assist it to take off, 'peel' off in flight and then return to port. My attempts here have recreated this concept however there are some issues that remain unresolved. Take off is achieved around 140mph, AG1 detaches the piggyback plane and this is the hard part. You need a fair amount of downwards pitch to get it to detach without clipping the inboard props on the Maia. This also unbalances the Maia and it tends to have unfavourable outcomes. I thought it was a rather neat concept that should be seen in SP!
