Ok lowerlobe why, in your view, is not passenger screening being carried out on London trains?
if 99.99% of pilots are not a security issue why waste resources searching them when the .00001% who may be would not get past the type of security check that MA indicates above...a database screening for the correct crew members?
You'll be happy to undergo a strip/body cavity search?
99.9999999% of people would not transport explosives in such a way but by you logic we should still be searched.
It would be interesting to see how you would react if you were searched in this manner everytime you enter your workspace
