Review by hipotok1978
Pros: totally awesome
Cons: U suck for being able to do it so fast
Review:
Just goes to show what someone can do with a futuristic space plane when they stop taking their pills


Review by lowerlowerhk
Pros: excellent piloting skills
Cons: Totally unrealistic
Review:
As a time attck, you made the flight very successfully.Very exciting and awesome. But in the respect of a simulator, it is extremely unrealistic. Unless earth will explode into pieces if I can't make it to Wideawake within 20mins, I absolutely won't choose your airlines lol!


Review by dgatsoulis
Pros: Undisputably the fastest pilot!!!
Cons: I can't beat your time!
Review:
I've given it a few tries and the best i did was 1096 sec. How the hell did you do that kick-ass landing? Just shift the COG back and hover?

Which vessel was used, please?

 

[Epsilon]

Although you could tell from watching the playback, it's an XR2.
And it's effing amazing.
*just got done watching -again-, 'cause it's just that cool*

XR-2

OK, for those of you that are thrill seekers (or just plain insane), [ame="http://www.orbithangar.com/searchid.php?ID=3669"]here's another flight[/ame] ("TT KSC-WIN - XR2"). It's in the same download as the first flight, but goes even faster. The flight is done in a gnat's whisker under 1000 seconds (16 minutes, 40 seconds).

Some interesting new points in this flight:

• SCRAMs are used right from takeoff as I wanted to squeeze every last drop of acceleration out of the XR2, and even on the runway at low speed, the SCRAMs deliver 80kN of thrust.
• The new flight keeps with the same supercruise profile of the previous flight (inverted flight to use the aerodynamic 'lift' to stop you flying out of the atmosphere, out of the Earth's SOI and into solar orbit), but goes even faster. The supercruise is conducted at ~73km altitude and at 15km/s (mach 53).
• The reentry profile is possibly the most insane profile that I've ever flown and can essentially be described as "Ass-first, face-down". The XR2 can withstand much more heat at higher angles of attack as you don't get heating on the top of the vessel as you're essentially performing a capsule-style reentry. Deceleration is much greater due to the larger cross-sectional area as you head into the wind. Also, as you can use your main engines whilst you are reentering to drop even lower into the atmosphere to get more drag to decelerate even faster - maximum deceleration was clocked at 9.5g
• Ignoring the runway and heading vertically down seems to be the fastest way to land. At about 1km altitude, quickly pull back on the stick and adjust the centre of gravity to quickly flip the vessel to a 90° angle of attack (level horizon) to once again expose the largest surface area to decelerate and then use the hover engines to land. In the playback the residual heat of reentry is still too hot and the gear coming out causes the vessel to explode, but this didn't happen in the flight itself. Don't know why.

For some reason, the racer checkpoint MFD shows 10s flight time when you cross the start line, so subtracting this 10s from the final time at landing (1005s) gives the sub-1000s time.

Thank you for flying psycho-muppet airlines. The fastest way from anywhere to anywhere...

And I thought 17 mins 25 seconds is on the borderline of impossible. Now will have to give it another try.

In the playback the residual heat of reentry is still too hot and the gear coming out causes the vessel to explode, but this didn't happen in the flight itself. Don't know why.

When you exceed the safe limits of the XR2, there is no guaranteed failure. There is a certain chance depending on how much you are over the limit.
So in some replays it will brake, in some it won't.

A very insane flight. I hope you never ever fly something in real life.

 

[Dambuster]

This is absolutely amazing!

there's lots of non-standard info in your .scn file, Agentgonzo, not very noob-friendly. I am talking addons that you don't mention, but arent' neccesary anyway, but do leave a couple of lines in the .scn file. No problem for me, but newer users might not want to go into editing a scn file if they expect it to work.

on the flight.. mach 53.. that's cool!

Which lines were those? I'll trim them out. For the second run, I started with the TT-KSC-WIN scenario from the ORL, so if there is extraneous info in there, then it's probably in the original addon <tries to shift blame...>

and prehaps this one, although ExtMfd is quite common, but I'm not sure how orbiter reacts if this module is not loaded but this line is encountered..

[agentgonzo]

OK, cheers. I'll remove them. The ORL and checkpoint ones are used for the racer league but I suppose that they're not needed for the playback. I'll remove them. Thanks for the info.

 

[kneejo]

you're welcome.. I completely understand the enthusiasm after accomplishing such a flight

 

[computerex]

For some reason, the racer checkpoint MFD shows 10s flight time when you cross the start line, so subtracting this 10s from the final time at landing (1005s) gives the sub-1000s time.

That was quite possibly the coolest flight I have ever seen. The landing at the end...MAN! You were heading down vertically while sub-sonic, I can't believe you pulled it off so "gracefully" Excellent flight.

BTW the MFD gives you a ten second penalty if you cross the start line without setting the status to "racing".

 

[Aldrasio]

This was awesome to watch. The entire reentry sequence was absolutely crazy, and I have to learn how to do that landing now.

 

[Chemi]

It is only k-a! because of KSC to ASC. sc LOL :lol:
