It has now been checked and can continue its journey to Birmingham.
Essex Police said military jets were deployed on a precautionary basis when the Latvian-registered cargo plane was diverted to Stansted due to a loss of communication with the aircraft.
The aircraft landed at Stansted at 5.20pm (local time).
All three people on board were been spoken to by officers and it was established everything was in order, Kent Online reported.
The reason for the short loss of communication was due to a change in airspace jurisdiction, the force said.
"Essex Police is not investigating the incident and the aircraft will be able to continue its journey to Birmingham when it is ready," a spokesman said.
Kent Police confirmed a "loud bang" felt by residents in the area at 4.44pm (local time) was related to the RAF activity.
People in Sevenoaks, Tonbridge, Tunbridge Wells and Dartford reported hearing the noise.
The RAF has apologised for "startling" residents after the planes were given the go-ahead to fly supersonic over land.
