That passenger was asking the pilot while walking through the parking area of that small airport:"Where is your plane?"
"See! Over there, the tri-motor plane” the pilot replied.
"I cannot see any tri-motor plane from here! Won’t you mean that blue and white?", asked the passenger again.
"Exactly, that is!" answered the pilot.
"Well," the passenger continued to say, "it only has two engines".
"That what I meant. If we lost one engine I'll try to land with the other” the pilot said while thinking as I had to do two days ago.
