A donkey engine would have stalled trying to pull Johnny around to the front porch, after that bald hint.
As it happened, Mary V was not taking any chances.

She was not on the front porch, but down at the airplane, snubbing Bland most unmercifully and waiting for Johnny.

When he appeared she was up in the front seat working the controls and pretending that she was speeding through the air while thousands gaped at her from below.
"I'm doing a make-believe nose dive, Skyrider," she chirped down at him, looking over the edge through Johnny's goggles, and hoping that he would accept her play as a tacit reconciliation, so that they could start all over again without any fussing.

No doubt dad had fixed things up with Johnny and everything would be perfectly all right.

"Look out below." "You better do a nose dive outa there," Johnny told her with terrific bluntness.
