7-Scouts acts as the pilot, co-pilot and radioman on an airliner. 4 other scouts are on the wings as the engines, on the wings of the plane.
The pilot announces to co-pilot that engine one has failed. Engine one (ham this up) sputters, makes noise and dies, Co-pilot instructs radioman to inform tower and tell them they will be arriving 15 minutes late(radioman radios tower and repeats message). Soon after engine two fails, repeat the process again but this time tell the tower they will be 30 minutes late. Then engine three with more panic tell the tower we will be 1 hour late. Finally the pilot announces the fourth and final engine has failed. The radioman then says: "Boys I'd better radio the tower, we may be up here all day!"
