What were they afraid of ? that you were going start trying to dismantle the plane in mid flight ?
I remember going to England years ago during the troubles , I was doing sound for friends so I took my electronics kit along just in case ,
wasnt worth the hassle in the end , having security eye me up and down like I was a bombmaker, I answered all their questions in a polite manner , in the end as I walked away I was called 'stupid Irish cunt' which I didnt react to at all , They were expecting me to get saucy with them and make their day . Of course I traveled to the UK many times without any issue .
