There are tens of millions of autos and light trucks on the road with open fuel pumps that run continuously while sitting in the gasoline liquid and vapor inside the vehicle’s fuel tank. This is perfectly safe. They cannot explode. The setup that Boeing has used for decades is just as safe.
The jet airplanes do not use gasoline for fuel. The kerosene, or oil, they use is not particularly explosively flammable, although it can be made to burn if the tank is already split open and fuel is everywhere.
The Boeing scenario is far safer, Jet A is far less likely to explode than gasoline.
Lol, my wife always screems when I fill my tank while the car is running.
I say, “Come one, when is the last time you ever heard of a car exploding because the engine was left running while fueling?”.
Also, most people are not aware that aircraft jet fuel is just KEROSENE.
Go to the store, buy some, build a wood pile, douse it with a gallon of kerosene, toss a match on it and watch how it DOESN”T explode.
Don’t do that with gasoline unless you enjoy a huge fireball and missing eyebrows.
Gasoline is explosive, kerosene is not. And don’t get me started about the ‘mythbusters’ episode... BS
The TWA 800 fuel tank is an order of magnitude safer. Jet fuel, similar to kerosene, is much less like to “explode” than gasoline at less than one atmosphere of pressure.
