One of the worst things that can happen to a field surveyor-a hurt ankle. The worst time it happened to me was in El Salvador, I was working on a road...

I like the albino roach!as for the dual prism method, as long as the rod can be held steady (one option is to use another rod to stabilize it, or rig ...

Dulles is not in the city, so it is easy to find. But, I know what you mean-especially smaller airports in the city, at night. I rented a plane a few ...

with really long runways (and multiple landings) it would be very difficult for the tower to notice.

They flew me through the localizer at the last minute, and then turned me southwest to intercept, I reckon it was for spacing on the parallel runway b...

Tyler: Dulles (and Gaithersburg) are in the ADIZ (Air Defense Identification Zone) but not the SFRA. I got fingerprinted at National last year, just n...
