Well, in December we went off to our place in Spain with my steel/steel ballistic Aeronaut as we have one for over two years without any complaint. On our return, my wife took a snap of me on my scooter while we waited for our plane at Alicante Airport. As you'll see, I use the ruck sack straps to sling the bag on the back of my scooter (Pride Go-Go Elite Traveller Plus). It's out of the way, but if I want something out, I stand up and fold the seat forward. The Aeronaut then sits on the folded seat, can be opened and, when you're done, just lift the seat and you're good to go.
