Who needs GPS when you have a star tracker and a current star map? It
worked for us with the SR-71.

Cool. We're having a little fly-in this weekend so you can bring your
SR-71 w/startracker and I'll bring my ultralight trike w/GPS...

Deal?

I'd be too worried about FOD at engine start with ultralight trikes
around. I guess we'll have to be sure the Blackbird is always in
front. Way far in front, unless the trike is titanium.
