Here are some questions for you.
Did X-31 join air show before? If did, when and where? Did it do any supermanuver in airshow?
It is better to post some photos or videos concerning that.
thanks in advance
Because I want to steal time from you since beginning ;D
It is joking,because I couldn't take next page in youtube, so I have to ask you to help.
Thanks for your help, I hope you will search a complete version of X-31 act in airshow. When I tracked the video to airshowpics.com, there is nothing displaied.
