On the SPTU concept may I suggest a little electronic castor that extends hydrolically from the bottom of the plane onto the tarmac where it then scoots you along in a nice zig-zag.
What I had in mind is something more simple, more along the lines of the pedalo boats you can hire at holiday resorts. This would incorporate pedals with a series of chains driving a sprocket attached to the nosewheel. It would give a wonderful zig-zag effect if attached to the rudder pedals but I haven't figured out the steering part yet. They could be fitted with a Sturmey Archer 3-speed unit as an extra. This could be used to increase power for short take-offs if required.

Once the idea takes off (pun intended) it could be extended to your charter airlines. The passenger seats would all be fitted with SPTU pedals & the punters could help pay for their cheap tickets by pedalling. A fierce looking chap with a drum & a whip would be there to encourage them, rather like the old Roman galleys. The more I think about it the more I like it.
