DC-6
The DC-6 you spotted was Air Atlantique's G-APSA or G-SIXC both have been at Dunsfold being filmed for the new bond movie as part of the 'Miami Airport' cargo area. Possibly last time they will ever fly, so hopefully plenty of people saw them doing there various beat-ups around the place. I believe departure out of Dunsfold was worth a viewing with the DC- 6 cleaned up 240kts with flight deck looking up at the tops of the lamp posts! If you've seen the lamp posts on the runway during 'Top Gear' you will appreciate the height!
Oh and for the comments about Top Gear.... how old do you sound!!!! Go get the slippers and dressing gown out, i am sure we can warm you a mug of hot cocoa!!
