Data Reliability and QualityFor more comments on the originator Malin Oloier and the technical equipment see case P-iFx3VIiQ0 description page. As I conclude in that case, there is no very compelling reason in the footage to doubt its reliability. However, we can also not fully preclude that this footage is a hoax.Close-Up View and Smear EffectThe low evening sun over a clear sky causes bright objects to reflect a lot of the sun light into the camera sensor. Therefore, the object appears very clear and bright, which is consistent with the other bright objects in the scene (e.g. the white roof tops and cars).Similar to other cases of possible WFM footage recorded with the same camera model, the smear effect is noticeable and weak (see figure 1 and case P-iFx3VIiQ0, Close-Up View for the related discussion). ![]() ![]() The object appears sufficiently large in the footage to observe its shape. Similar to the other case of possible WFM footage from the same originator the object does not seem to have a distinct and stable shape. As Figure 2 shows the object shows a cloud-like morphing behavior. However, the morphing object does not seem to be subject to distortion by drag against the air. Fig 2. Cloud-like morphing behavior (zoomed version by originator, 2.3MB, 1280 x 1350 pixels)) Travel PathThe originator already provides a detailed analysis of the travel path (figure 3) with which I agree after framy-by-frame analysis.Similar to another case (h0s_P74oQD4) the object seems to significantly lower its altitude before passing the drone. The object does not follow the parabolic trajectory of a falling object, indicating that it is propelled. After its decrease in altitude early in the footage the object seems to remain on roughly the same altitude. Estimation of Travel SpeedEmploying the standard methodology with an estimated travel distance as shown in figure 4 below, we can infer a travel speed of about 1,638km/h. However, in this case this estimate is particularly unreliable, because the visible travel path in the image indicates a noticeable change of the object's altitude.However, on the other hand, as figure 1 indicates, a smear effect consistent with such a very fast moving object shot with a Sony Exmor sensor is visible. Weather ConditionsIts a very warm summer day with only weak wind. The phenomenon cannot be explained as a mundane weather phenomenon.Appendix![]() * Geographic coordinates are given as a vector of latitudes and longitudes in format WGS 84 as used by Google maps. † The detailed point in time of the capture was stated by the originator of the footage. |
