I got sopwith.exe from my uncle's "big blue disks" subscription. plus a lot of other racy games an 8 year old shouldn't have played.
I tried playing a copy on a modern computer and the game started and finished on its own in about 1/4 of a second! i'm not that fast anymore!
I got very good at dropping the bomb while upside down and then flipping and getting outta there. i was also obsessed with disney's tale spin and imagined it was the seaduck.
