I think you might refer to two separate incidents :


Early January 1945 : A pair of 176 GvIAP La-7s (Mayor Kumanichkin and Polkovnik Chupikov) equipped with guncams encounter 2 Me-109 carrying something under fuselage and Chupikov attacks them, but the Germans manage to outrun the La-7s and, after examination of guncam films, ingeneer Zaritskiy consider the centerline carriages (first thought to have been bombs) to be something like a Jet booster.

19/02/1945 : Kojedub claims Me-262 (sometimes said to be that of Uffz Kurt Lange from 1./KG(J)54)
