I should say, by “clearly not practical” I meant for conventional systems like the shuttle or a Titan - these require a lot of ground based infrastructure. There are other launch systems that launch from aircraft flying higher than that - the Orbital Sciences Corp Pegasus(?) is one that I remember off hand.

There have also been proposals floated to use balloons to lift something in a similar manner.
