Aircraft over North London
Hello
Sitting outside a pub in North London yesterday evening, I saw several commercial aircraft (both narrow and wide bodied) flying overheard in what I think was a northerly direction. The aircraft appeared to be at/below 10,000ft (I know it's not possible to tell). In any case, quite "low".
Could someone tell me where they were flying to? I assume they weren't Luton-bound as there were a couple of 747s. Were they leaving a hold? Or were they in fact departing from LHR? If so, why were they still quite low over North London?
Many thanks
Nick
