Drones are dropping from theskies like ducks on opening day just as the U.S. and the U.K. are preparing to approve the mass invasions of their tello. Large unmanned aerial vehicles (UAVs) are crashing to the ground nearly every month. Smaller UAVs are crashing almost every day so it's almost impossible to keep records on their mishaps. The pilotless and sightless birds will present a dire threat to commercial and private aircraft and to life on the ground. The Civil Aviation Authority (CAA) in the U.K. and the Federal Aviation Authority (FAA) in the U.S. seem oblivious to the danger as they move ever closer to approving the invasions.

On August 24th three large drones hit the decks in a single week with two of them landing in highly populated areas.

On August 15th an RQ-7 Shadow drone collided with a U.S. Air Force C-130 cargo plane as it was flying near eastern Afghanistan. No one was injured in the crash as the C-130 was able to successfully land after the crash. In this case the manned aircraft overtook the RQ-7 while it was in a holding pattern. Just four days after the midair collision an unknown drone crashed in the capital city of Mogadishu in Somalia. It is suspected that the drone was operated by the U.S. military. No word was published on whether people were injured on the ground. The same press report indicated that the Somali government had confirmed five crashes in the same 24 hour period.

On August 20th a third drone crashed into a residential neighborhood near Jalalabad, Afghanistan. The drone was operated by NATO's International Security Assistance Force (ISAF). There were no reported injuries on the ground.

On August 25, 2011 an American drone dropped out of the sky near Chaman town in Baluchistan, Pakistan. The crash caused no damage according to a security official at the site. The UAV was said to have crashed due to a "technical fault."

Disarmingman, writing for globalresearch.ca, claims that there were 36 (now 37) large drone crashes between 2010 and 2011; and nearly 80 since 2007. He tracks them and provides links to the press reports for all of them.

Up to now unmanned aerial vehicles have been restricted to temporary compartmentalized airspace, but many of the approved airspaces are in close proximity to civilian and military airports where the dangers of catastrophic collisions are more likely than in isolated areas. Current 'sense and avoid' technologies used in piloted aircraft are not suitable for UAVs. The wide range of sizes, speeds and maneuverability make the design of a universal 'sense and avoid' system for UAVs extremely difficult. Many small manned aircraft do not use transponders.

They operate using visual sight rules eliminating the 'sense and avoid' technologies used in larger commercial aircraft. Video data does not provide enough distance information for unmanned aerial systems to effectively avoid collisions. MITRE is researching a combination of radar and electro-optical elements in their efforts to come up with a suitable 'sense and avoid' solution. Testing is being done using radio-controlled aircraft but even that testing has proven to be dangerous.
