But after all, this was someone else's private affair, so he didn't say much more and turned to introduce his proud creation.
"Your glider's launching device is a bit too old; most gliders today use propeller start-stop systems. I've equipped you with a new launching device that uses a turbine for traction, allowing for an ejecting pull to start the glider, but it requires a relatively smooth surface, so I chose to park it on a flat road."
Allen Zhang looked at the launching device, a facility separate from the glider itself; it needed to first start and pull the glider to run, taking advantage of rising air currents to ascend steadily. He asked doubtfully, "Do we have to pack up this device after using it?"
"Of course. It's not disposable. Didn't you drive here? But there are only two of you, how do you plan to go back?" Mark inquired with confusion.
