You’ll have an hour and forty minute layover at the connection point before continuing on to London Heathrow. All in all you’re looking at two nonstop flights, both operated by two different four engine jets on two different airlines. Identify the airlines, routing and the two different aircraft types.
A BA Concorde is involved, but not through JFK

BA also operated the Concorde to LHR from Washington Dulles/IAD; as far as a four-engine jet running ATL-IAD, we have to be looking at Presidential Airways (XV) with a BAe 146

That's correct. In any event, I don't think Delta ever operated its DC-8-61/71s into Dulles though it did once operate its standard DC-8 during the early days of the interchange flights with Pan Am. But I digress. Here's the itinerary -

Presidential Airways XV Atlanta (ATL) 930a-1120a B Washington (IAD) BAe-146-200 Daily
British Airways BA 188 Washington (IAD) 100p v -1000p London (LHR) Concorde We Fr Su
