Whoa, what's that? An aerial vehicle identifying itself as a British #GrobPrefect military training aircraft of the #RoyalAirForce has been spotted over Western #Ukraine, between Lviv and Ivano-Frankivsk.
However, the #G120TP is not capable of flying faster than 245 knots, so either the alleged speed of 431 knots (ca. 800 km/h) was measured in km/h and was wrongly reported in knots, or it's a different aircraft type.
