CC,
Such an operation happened. Both in Burma and for medical evacuations in Europe.
Recommeded reading: "Silent Wings at War," by John Lowden, an excellent accounting of the combat glider program.
The British glider program was is particularly noteworthy and filled with brave folks. Pegasus Bridge being, probably, the most famous exploit.
I did a magazine story on a US glider pilot (Flight Journal, Jan 05). This guy flew a Brit Horsa into D-Day, then Wacos for two other ops. Non-combat flying included the medical evac of wounded via the method you asked about.
Took guts!
