Final answer:
The pilot would most likely perform an emergency landing and may use an emergency slide or activate the fire suppression system. Contacting the control tower is also important.
Step-by-step explanation:
When the plane caught fire, the pilots would most likely perform an emergency landing to ensure the safety of the passengers and crew. This is because an emergency landing allows for a controlled descent and landing, minimizing the risk of a crash or further damage to the plane.
Using an emergency slide or activating the fire suppression system may also be necessary depending on the severity of the fire. The emergency slide can provide a quick and safe exit for passengers, while the fire suppression system helps to extinguish the fire and prevent it from spreading.
Contacting the control tower would usually be done as part of the emergency landing procedure to inform the airport authorities of the situation and receive instructions or assistance if needed.
