Now, each airport works out separate security requirements; very few, if any, require physical screening of the full array of workers like airplane cleaners, mechanics and baggage handlers, according to Mr. Schumer.
I find it rather ironic that to comply with requirements of flights TO the USA, our airport has some rather draconian security measures (even for the staff). They even look inside McDonalds lunchboxes. One security guard even looked through the pages of a young engineer's experience logbook (about a quarter the thickness of a paperback).
