Not quite on topic, but a developer in San Diego got a permit to build a "sky scraper" in the path of an alternate landing pattern, just out of the airport authority. End result? The developer had to
Not really fair to repost part of an article and comment on the part not repeated. The first link provided the developers view. August 12, 2007 hardly qualifies as 'very old' when discussing planning
Too many die in low trenches and holes. If the soil is above your hips, and you bend down and are covered in a wall collapse, you may die. Others have. It's like climbing without a belt. http://www.c

Jim, I think it is relevant in that a well known bridge system would have been less likely to fail = follow the manufacturer's recomendations. An un-tried design is more likely to fail--and the failu
I'm feeling really dense this morning <grin>, but I'm thinking the easy way is to use a compass and take the bearing from one tree to the other, and add/subtract 90 degrees. Accuracy can be near one
Hi Doug. I would recommend checking with local warden to let them know what you are doing and to keep them informed. They may offer advice or assistance. The fact that you have allowed the birds to n
Might also be useful to provide some conceptual information on what the engineering costs and why. Perhaps some range of time an engineer has to consume to get typical jobs done, and the risk an engi
