Alternatively, muslim only flights / airlnes
Until people start to behave
I like that idea.
I will get my surface to air rocket ready.
Ok, I know this isn't the place for politics and the mods can remove this post if they want to, but....
Lets not tar everyone with the same brush here.
What we are talking about is extremists hanging on to the Muslim faith, not Muslims in general.
Cat Stevens and Imran Khan are Muslims and I don't think they are likely to be looking to blow anything up.
The IRA used to blow things up in London, they are 'Catholics' and the UDA/UVF used to murder people  and blow things up in The North they are 'Protestants', but we didn't  call for Catholic/ Protestant only shops and bars and then make comments like "I'm ready with my grenades". 
My family are Catholics but I don't inmtend to go out and blow up a Protestant.
Yes the people responsible for 9/11 and this plan are evil and deserve to be hunted down and dealt with but they do not represent the Muslim faith in general..
A little tolerance goes a long way in this world.
