Yes, I built that one, but the one I'm talking about looks similar but is a WW2 German bomber that was to fly one way to the US, bomb their target and parachute out to be recovered by U-boat. It had jet engines on the top of it.
I was a big fan of the hypothetical planes of the 1980s and 90s. The Testors F-19 and MiG-37 Ferret (my personal favorite), the Stingbat stealth helicopter, this B-2 stealth bomber and the Testors Thunderdart and SR-75 Penetrator. This last one was quite a setup. One day, I should finish it.
