Military high level VFR?
Hi, this is an slf (with ppl) with a question:
was passenger on a flight yesterday. Flying at fl 400 westward over Hungary we suddenly saw some 5 planes, looking military (probably c17) coming exactly the opposite direction, slightly lateral offset but vertical separation was extremely low. Could that have been military vfr at fl 395? Weather was perfect vmc. Looked really scary to me ... ...

There is normally no VFR above FL290 in Europe (*) and definitively no 500ft VFR crossing separation either , so most probably it was 1000ft which looks extremely close , definitively if it was a C17.
Note (*) exceptions for record flights in designated areas activated PPR. ( a couple are above the Alps to allow gliders records).

Formation flights
I don't know specifically UK and C-17, but generally it is possible to fly IFR as a formation, where ATC treats the formation as a single entity and the planes in formation are responsible to mainitain mutual separation (and a standard or a non-standard formation). I would guess that aircraft in question were flying IFR formation.
I can't post links, but search with "formation flying" should bring up the regulatory base for this.

Although most nations impose limitations on the volume of airspace which may be occupied by formations, there is no universal definition of formation dimensions. ICAO provisions are that all aircraft within a formation shall operate so that the wing aircraft maintain a distance of not more than 1 nm laterally and longitudinally and a vertical displacement of not greater than 30m (100 ft) from the flight leader. These limits may only be exceeded at the discretion of ATC or when flying within the vertical airspace block assigned in an ALTRV.
