At least you can comfort yourself now with the fact that you saw one of the mighty beasts before they were gone.
For those not lucky enough to have seen the SRN-4 in the flesh, the pictures don't do it the slightest bit of justice. But some the Youtube vids do - search them, get them up, punch full screen, turn the volume up until somebody complains (and then a bit more).
Which made me think. What (ignoring snarky whiners' "humour") is our heritage of tomorrow? I remember Deltics, SRN-4s, Concorde, Chieftain tanks, Nimrods, a whole host of classic military aircraft (Canberra, Lightning, Hunter, Vulcan, Victor, Harrier). But what is there now that we will be able to say to our kids "Eee, lad, that were great British engineering, that were!".
