Due to the length of the Monsoon I am unable to gain permission to fly an Open Cockpit Gyro through parts of Canada and Greenland.
"Unable to gain permission", sounds pretty no-ish to me.
I see, they haven't said No, just that you can't do it. OK..!
I saw that comment on the message boards on the GE website also, (I have never posted there, I hasten to add), but there's no reason to react like that and don't give up just yet. Most of us would like to see you complete the round the world trip than not finish it at all.
Compare it to Paula Radcliffe. She would have more respect from the public if she had finished the Marathon, albeit way down the list, than give up after realising she wasn't going to get a medal.
As I asked before, what is the timeline from Alaska to UK?
In the words of Kate Bush......."Don't give up".
