Field marks

  1. If you see a 747 today, odds are it is a freighter — check for cargo doors and a windowless main deck
  2. Front hump with a second row of windows above the main deck, shorter than the 747-8's extended hump
  3. Upturned wingtip blade distinguishes it from any earlier 747 classic still occasionally flying
  4. Four engines under the wings rule out every widebody except the 747-8 and A380

Size and shape, to scale

Photos can't hold a consistent scale from shot to shot — these silhouettes are all drawn at the same 10 px = 1 m scale, so the proportions here are trustworthy even though the photos above aren't.

Variant notes

  • Most surviving airframes are 747-400F/BCF freighters — passenger -400s are increasingly rare outside a handful of legacy carriers
  • The -400 was the first 747 with upturned winglets standard — earlier classics (100/200/300) had plain tips and are essentially gone from service
  • Three engine families were offered; engine-pod shape and size look similar enough across all three that engine choice is not a useful spotting cue
