Spaceplanes

How high did you get your space plane on sandbox mode

0 meters

[Atkara]

Everyone starts with 0 meters. Things get better later on 

[KerikBalm]

a sideways 8, in other words: to solar escape velocity

15000 metres

50k, before it stalled and nosedived.

[Artienia]

Nice!

[Tom kerbin]

wow im following you

[KerikBalm]

Technically speaking; if a plane doesn't get over 70km for the stock game, then its not a spaceplane.

[suicidejunkie]

Technically zero.

But in career mode, I've cleared Kerbin's SoI on training flights and it could escape if I wanted to try.

My first sandbox spaceplane I'm pretty sure bounced when it went sideways on the runway before coming apart, so 1-2m maybe

As Orville Wright said,

"it's not about altitude or speed, it's about control".

I have built dozens of highly successful SSTTPEOKs*.

[luizopiloto]

this one is the best I have made so far...

I've got a couple on Laythe in career mode. Haven't gone past that.

[TheKSPBeginner]

I've only gone to space. Just space.

[Zeiss Ikon]

If we count only HOTOL, I've gotten as high as 40 km, on a flight  that went halfway around Kerbin.  If we included vertical launch, I used a spaceplane orbiter for LKO and Munar flyby tourist missions; even attempted a Mun landing (aborted due to low fuel).

Of course, I've really only designed/built spaceplanes in my current career.

I don't use Sandbox much, but on an earlier career I was using a small spaceplane as a training bus to take rookie crews to the Mun and Minmus, but it did have to go via an LKO station to refuel.  I don't really see the point of them beyond launching/landing on worlds with atmospheres though, having docked with the station to refuel it would have been more efficient to take a conventional lander to the Mun and Minmus than carry useless wings and air breathing engines all the way there.

I've also had a fair few that didn't make it as far as the end of the runway though.
