Don't click on the wing.
Many airlines give passengers the opportunity to select a preferred seat when booking a flight. In this case, Megan appears to be checking in at a self-check-in at the airport, where she is given the opportunity to select her seat. Rather than selecting a seat on the diagram, Megan clicks on the pilot seat (which is of course not an actual option for online seating reservations)[citation needed]. In the last frame, we see that, because she chose the pilot seat, she is now actually sitting in the captain’s seat, flying the plane while whooping. A worried-looking pilot sits behind her at the back of the cockpit, holding both hands in front of his mouth in shock. While she is flying in a presumably fully-enclosed cockpit, her scarf rises behind her as if being pushed by a great wind. This is likely to show that she is piloting the aircraft recklessly compared to a normal pilot, as her scarf would only rise like in the comic due to a large amount of Gs being exerted on it.
The title text says to not click on the wing. The implication is that if you did click on the wing you would, similarly, end up sitting outside on the wing. Even if you were able to hold on, this would put you above the Death Zone, which is at 7 km (See the what if? article Rising Steadily). Standard cruising altitude is 10 km (30,000-39,000 ft.). It would be an unpleasant death, as the air is so thin that you actually lose oxygen to the air (as explained in the mentioned what if?). 2862: Typical Seating Chart lists such wing seats as seating space opportunities that are wasted by some companies and two wing seats at the extemities of the wings, for "lookout" purposes.
This kind of event could lead to situations as the one depicted in 1660: Captain Speaking. For this reason, 2862: Typical Seating Chart requests that non-pilots do not select the pilot seat(s).
