In the book Old Yeller was a Black Mouth Cur. Black mouth curs were not uncommon in the earlier USA days (âwild westâ days) in the southern USA (Texas, etc.) and could have been chosen as the breed in the book because it was recognized and it was a common hunting companion dog.
The cost per flight hour varies by type of drone. Predator and Reaper drones cost about $2,500-3,500 per flight hour; larger armed systems such as the militaryâs Global Hawk cost about 10 times as much: approximately $30,000 per flight hour.
The unit cost for one Predator is about $4.5 million, according to DHS estimates. But the costs of operating a UAV can become more than double the costs of operating a manned aircraft, said the Congressional Research Service (CRS) last summer.(See Homeland Security: Unmanned Aerial Vehicles and Border Surveillance.).ased on that figure, keeping one UAV in the air every hour of the year would cost about $28.5 million. Homeland Security Todayâs Mickey McCarter has written the most thorough piece on SBInet that I have seen in the past several years.
