Tom Swift And His Air Glider

"Well, Ned, are you ready?" "Oh, I suppose so, Tom. As ready as I ever shall be." "Why, Ned Newton, you're not getting afraid; are you? And after you've been on so many trips with me?" "No, it isn't exactly that, Tom. I'd go in a minute if you didn't have this new fangled thing on your airship. But how do you know how it's going to work - or whether it will work at all? We may come a cropper." The motor cycle came to a stop near a shed, and the two lads, swinging off, looked at each other for a moment.
