Second generation 250 seater solar powered passenger plane !

Is on its way as we speak, but I cannot show it to you. It has same elements with few new ones as the earlier ones.

Solar/rocket powered passenger plane of 80 seats !

Mach 2+ at 50-60 km....and as glider down to 40 km altitude and back to solar powered flight.
Also a 100 seater with 68 m span.

56+2 seater Solar Impulse like spanning passenger aircraft !

This could be the first step towards electric/solar powered passenger aeroplane !
I am pretty sure it has to have 2/3 of the accu power.

Comparison with SKYLON and APOLLO !

It is not small..but it flies slowly in low atmosphere ( 50-200 km/h )when it gets to Stratosphere it could go 700-2000 km/h and finally in Mesosphere 4 000 - 15 000 km/h..in Thermosphre it goes like any other..25 000 - 30 000 km/h.
I assume it is the best to jettison the space rocket at 120 km when there is still some air where the elevator can be used to initiate the landing phase as a glider.
