In 443 cases (74%) these UAP are described as "objects" (42% circular-shaped) more than as point sources of light. In 162 cases (27%), the visual observation is confirmed by detection by ground and/or airborne radar. This report focusses more especially on 290 cases (48%) in which UAP have had (or could have had) an impact on flight safety. In 108 cases (37% of the 290 cases), pilots have estimated that the impact on flight safety was high enough for them to submit an official Airmiss/Airprox report. It was found that the most reported events with potential impact(s) on aviation safety were: "UAP approached aircraft on a collision course" (78 cases) and "UAP circled or maneuvered close to aircraft" (59 cases). It was found also that in 81 cases (14% of the 600 cases) pilots reported alleged electromagnetic effects on one or more aircraft systems. Radio and compass systems were the predominant systems affected. Private aircraft were more affected by the E-M effects (alleged caused by UAP), probably due to the fact that their avionics and compasses are less shielded against magnetic/radio frequency interference and ionizing radiation than are commercial or military aircraft. It was found that in four cases military aircraft weapon systems were momentarily ineffective when targeted towards the UAP. Finally, in 31 cases pilots had to take evasive action to avoid a collision with UAP, injuring several passengers in five cases. These findings are potentially important and deserve further in-depth study and confirmation by obtaining additional high quality aviation reports.
