Look at what's going to happen next year...
...as predicted in this tale published in the third and final issue of Ace's sci-fi anthology, Space Action (1952)!
At least this tale, illustrated by Lou Cameron, offers an explanation as to why time travelers haven't come back to the past.But, I find it difficult to believe the people of the future couldn't retrofit a vehicle with still-functioning (though centuries-old) technology with a control device.
BTW, the writer is unknown.
