Richard Scarry's A Day at the Airport (Pictureback(R))

Sally, Huckle, and Lowly are supposed to go sailing with Huckle and Sally's father, but it starts to rain. Father says they will have to stay inside and play, but their friend Rudolf von Flugel saves the day when he picks the kids up in his airplane-car and whisks them off to the airport for a fun day of sightseeing. Full of airport fun and "Scarry" mishaps.
