I would not worry about the gates. If you manage to get onto an area where the aircraft are, you will have board and lodging courtesy of the government, for several years.
You will go to prison, where electric gates will be the least of your problems.
If you are in the cabin you will be found, if you hide on the outside of the aircraft, you will die!
There's no way you will get past security to get to the boarding area much less get close to a gate or on a plane.
Sure, whatever little boy.
got nothing to do
...........What?
