One technique to launch underpowered self-launchers is to auto-tow the
ship until it is airborne and then climb under power. The
acceleration and ground roll can be a significant problem at high
altitudes or on soft fields and the auto-tow is cheap and simple.

Bungee launch without the hill! That would enable you to launch
unassisted: stretch the bungey out the runway, climb in, trigger the
release of the bungee, and WHHoommp! You are going 45 knots and off the
runway.
