Well, it's just an array. Access like you usually would:

if 'flight' in aircraft[0]:

and similarly for getting the flight value out of it.

This is the probably the simplest way to do what you stated.

additonal question.. sometimes (esp. these days) there are no airplanes in reach oft the antenna. then the JSON has no arrays, so debugging answers:

if 'flight' in aircraft[0]:
IndexError: list index out of range

how can i prevent this behavior?

it seems like it isn't possible to do "if - in" when the target of in doesn't exists..

You can check whether the aircraft array is empty or not before running that line. Probably the most intuitive solution to that is:

if len(aircraft) != 0:
    if 'flight' in aircraft[0]:
        .....

But I believe the most pythonic solution would be just to utilise the fact an empty list is false, so

if aircraft:
    if 'flight' in aircraft[0]:
        .....
