I managed to submit it. I had to put in 1 hours flying, some made up dates for starting and finishing in all the mandatory field boxes. I then inputted NA for the airline I had worked for, NA for the shcool etc.
If you put n/a it won't work.
I am hoping they will relaise that this data is false to just get the form to submit. Good point is it may mean they have had few applicants!
