They went one better than that, here in the UK....
A TV show "Top Gear" lauched a car on a exact replica of the Space Shuttle SLB and Fuel Tank about a mile or so into the air. The car had wings and was meant to seperate and RC fly back it to land. Unfortunately the explosive bolts didn't go bang and it came down with the booster unit.
It performed a perfect launch, however.
The Car??
A Reliant "Robin"!!
