This week the USAF released an accident investigation report into the crash of a US Predator drone in Afghanistan in April 2012. This crash brings the number of drone crashes in our updated database to 100 (see full database here) and so we thought it a good time to do some data crunching.
Our database primarily contains details of crashes of Class 2 and Class 3 UAVs (i.e. medium and large drones – see here for explanation of drone class and size) since January 2007. However there are a few occasions when small drone crashes have been included for some notable reasons (i.e. crashed with another aircraft). We continue to maintain this database as, although safety and reliability is a key issue in the growing use of unmanned aerial vehicles, nobody appears to be publicly compiling drone crash information. We are not claiming that our database is complete. Given the secretive nature of drone operations and development, it is highly likely that other drone crashes have occurred and not been publicly reported.
So far this year we have recorded 14 crashes involving 15 drones (yep, one crash involved two drones colliding). However it should be noted that one key source for our data – the USAF Aerospace Mishap Website – has not been updated since December 2011 and this may well have impacted upon the figures (see Table 1: Drone Crashes by Year).
Unsurprisingly the largest number of crashes in our database (40) have occurred in Afghanistan (see Table 2: Drone Crashes by Country). Of these, 29 have been USAF drones, 5 have been acknowledged by NATO ISAF but no further details have given; while 3 have been Canadian with one each lost by UK, German and Australia (see Table 3: Drone Crashes in Afghanistan).
It may surprise some to find that as many drones – 18 – have crashed in the US since January 2007 as in Iraq. In 2010 alone, seven drones crashed in the US – one was a small Mexican surveillance drone that crashed into a house in Texas, the other 6 crashed during military training flights or military company test flights. Given the fact that earlier this year the US government mandated that US skies should be opened up to civil drones by 2015, this figure is only likely to increase. No drone crashes have been reported in Iraq since 2010.
The next countries with the highest level of drone crashes on their territory is Pakistan and Djibouti, both with four drone crashes since 2007. Two of the drones that crashed in Pakistan were operated by the Pakistan military (probably Jasoos, but not confirmed) with the other two crashes reported by Pakistan military and intelligence officials to be US drones. It is certainly possible that other US drones have crashed in Pakistan and not been reported. One entry on the USAF Aerospace Mishaps website in August 2007 records the crash of a Predator drone being operated by US Special Forces but gives no more details.
Four US Predator drones have crashed in Djibouti, all in 2011. Djibouti is reported to be the main base from where US drone attacks in Yemen are launched. In Feb 2011, AFP reported a US drone crash in Yemen itself. According to the report, Predator drone wreckage was recovered by the local police but then hijacked by Al-Qaeda gunmen.
Drones just don’t crash in war zones, as our data shows . India, Italy, South Korea, Wales and China have also seen such crashes, signifying the growing proliferation of such technology. The crash in South Korea, for example, killed a Finnish engineer, working for an Austrian company demonstrating a drone to the South Korean military.
However the data also shows that two countries continue to dominate the production and export of drones: USA and Israel (see Table 4: Drone Crashes by Manufacturer). Out of the 101 drones that have crashed, 71 were known to have been US drones and 9 were known to have been Israeli.
Both in US and in Europe corporate interests continue to pressurize governments to open up civilian airspace to unmanned systems. Without a real improvement in reliability and safety however, legislators should remain sceptical, else we really will be living in the Century of drone crashes.

Who (or what) can I sue when one of these things crashes into my house? If the answer is nobody, then these things have no right flying around my house in the first place.
