Water seemed a little warmer for this time of yr, was 82-83 f. coming in, no problems, going home, some pias. signed up for the US air CC to get first class check in, well no first class check in, use the keyas (sp) sir. going thru security, I had 2 3" screw drivers and a small cresent wrench in my carry on. I really know to put in check threw but forgot, any way I thought in the states you could take small (less than 6") tools in carry on. Sir you are not in the states, you are in the UK, no tools.
