About this creation
I forced myself to finish the aircraft before I will start my new job on Monday.
From then on, I will have a lot less time for building.
This thing represents something between a wide-body and “mid-body” aircraft design: its fuselage diameter is supposed to be smaller than the DC-10 / MD-11, but a tad wider than B-707 and Co. Roughly the diameter of the A-320 series, but “stretched” in both length and wing span in relation to those Airbus planes…
I like long, “sleak” planes:)…
This model was the most difficult one I have built so far, particularly due to the incredibly complex wing structure: not only did I have to hang the engines underneath the wing in an awkward, untypical way; moreover, I included working Kruger flaps (expandable leading edge flaps), increasing lift during the take-off and approach phase:
I don’t think this has been realized yet on any Lego aircraft model – but feel free to prove me wrong!
To Jonathan Ma:
As promised, I will include some pictures of how I made the doors of the aircraft at the end of this page.
I hope you´ll enjoy:)
It has a pretty nice tail:

Adding the stairs to the halted aircraft for an upcoming boarding procedure:
Some celebrities will be among the passengers: here, we have Pink posing with the "Team Deutsche Telekom" Tour de France stars!
In the meantime, the general boarding starts, but is slowed down immensly by an additional customs control:
Weird ravers or a neo-modern cult? Who knows! :)
Look who else is on this flight... :)
I especially enjoy this kind of perspective here:
The above mentioned Krueger Flaps, increasing lift during the critical phases of take-offs and approaches:
A heavy Sojourner touching down...
The underside of the fuselage - sorry for the flash light - it was too dark to take better pics...
The next one shows the nose shape quite well. I tried to make a nice, sleak-looking, rounded nose, representing some of the main features of most real aircraft of medium or large size:
Once more the frontal view of the Sojourner:
An easy-to-open cabin for playbility purposes:
The front section of the cabin (1st class) and the door to the cockpit:
Rear section of the cabin:
There are different cargo options for the Sojourner: It has space for two small belly containers...
... or a large cargo bay on the main deck for all sorts of bulky cargo or two 4*8, 4-brick-high containers like shown on the following pic:
A optical, sizw-wise comparison between the P-1 and the P-2:
Last but not least, here's how I build aircraft doors. It's very simple, similar to how it is done on the original Lego fuselages:
Ratings, comments and constructive criticism are appreciated!
I´ll gladly answer to any questions, but won´t be able to check my account until Sunday evening...
Seems very sophisticated, keeping with is a sense of reality. Constructive criticism: The nose seems directed quite upward. Was this the original look? I'm not a plane expert. Also, I you have less time to build, try flying boats. They are blocky and very square, and are easy to make, even with a limited or basic set of pieces.
@Jeff R. and others who don´t like the nose: As I explained further below, I won´t change the nose, as I find it beautiful. It´s not perfect, but I havn´t seen anybody´s attempt of a rounded aircraft nose which I liked better than my own. It took me a long time to make it, and I still like it. For that range of width of an aircraft, that´s my preferred solution.
hi steffen! hey, i found a guy you d like to meet! he builds a sub! you HAVE to look at his work, as he shows the same passion towards building revolutionnary concepts of techniques, but, on a sub, you can erase this once red, as you did nt post anything new to comment on, good luck on your next project steffen!
@ Jonathan Ma:
Thank you, Jonathan!
Which ones do you mean, the ones on the backside of the wing and the tailplane, or the leading edge flaps?
For the first ones (wing backside and tailplane), you can see some pretty good pics. For example, consider this one:
For the Krueger flaps (leading edge flaps), no picture can really show how I did it. The technique for the Krueger flaps is based on tiled sections, put upside down towards each other, but built in fixly into the general edge... Hard to explain, and even harder to photograph! They were extremely difficult to integrate into the entire wing due to reasons of wing structure and stability. The technique was necessary because the hinges I used had to show their studs to the ground. Only like that, the flaps would fold out towards the edge (and prolong it) and towards the ground at the same time. Best regards, Steffen
Excellent work Steffen! I love the entire aircraft! My friend Josviel absolutely loves any type of aircraft, and I just sent him the link to this page. I will post a comment with what he has to say later. I am always amazed with all your aircraft! I love the cargo containers on this airplane, how many suitcases do they hold? Very nice work, and could you check out my medevac airplane?
Dear Frank, thank you very much for your very nice comment!
I am glad you like the model. Frankly, it was the most difficult one I have built so far, and the most complex one when it comes to building techniques. Although I think that nothing will ever get perfect in Lego, because there are certain unavoidable flaws (like the imitation of rounded sections of aircraft). Some people have critizised the nose, and my guess is that this is what you meant with "looking rough". Though again, I think that both nose and tail are my best ones so far, as they include a continuous, narrowing flow of the fuselage on the sides AND stepping from both on top and below (in contrast to the Falcon´s nose and tail sections, which were purely based on stepping of slopes, plates and bricks).
I would love to set up an airport layout already, but we have a space problem in our current, very small appartment. So I´ll have to focus on aircraft and some vehicles for a while. The amount of pieces I own actually isn´t too big of a problem - I benefit from a huge childhood collection plus some more recent acquirements from some pick-a-brick wall visits:)... It´s just time and space that are insuffucient to realize an entire layout right now.
The little baggage truck, I kept it small on purpose. Most of those, in reality, look small, old and very basic- so I kept it in 4-wide and stylictically simple. Nonetheless, that little thing is tons of fun to play with:):):)
Anyways, thanks again, and we will talk soon!
hi steffen!,i did my homework and had a closer look at the official airport and airliners from lego,ok,they look like privateers,compared to yours,it s obvious as soon as we look inside both interiors!,what you ve done is nothing short of fantastic!
i still havethis phantassy where i m rich,and send you 4 airport kits,but,it s my problem,hurrmm,i really liked the pics with figs!,it really brings life and color to your presentation,i miss the rest of your setup though,i hope one day ,you ll show the whole airport planes set up!,i know it s a lot of work,[look at my set ups],but,well worth it in the long term!,especially if you keep in the town category,some buildings are appreciated,i love your baggage trailer vehicles,it looks great and vintage,especially the tractor,i love it!,i m quite fond of that design,as it reminds me my youth kits!,and still look pretty good in some present applications!,your building technique is ever improving,although some part of the planes are still looking rough,i can see the day where you ll reach that spectacular 'merveille!',i m sure you re the best airliner builder in the world now,if not,i d be surprised!,refining,and deepening,and back to the drawing board,i know you ll do it all!,as i can feel you re very determined!,i support your effort!,as it s very hard and astute work!,you re always welcome to visit cybercity my friend!
Thank you so much, guys! I am overwhelmed by all your positive feedback. It makes me want to contiune building so much. So one day, maybe, my airport layout will be complete... :)
Best regards, Steffen
@ Mirq Vaspir: Thank you very much! Yeah, the gear fully retracts and is built in a similar was as the Falcon´s landing gear - you can check it out on the Falcon´s page, to where I added a close-up of the gear. For the Sojourner, I fixed the gear with a few tiles which cab be taken away easily, due to the massive weight... Just to make sure that really nothing can fold in while one pushes or pulls the aircraft on the ground.
Thank you for your comment, E.K.O.!
Yep, two pilots! The cockpit was too hard to photograph as their wasn´t enough light, and I was too lazy getting the pilots out at the time. But yes, the cockpit also holds minifigs!
And the cabin holds 40 passengers...
AMAZING...I can't believe I'm just discovering this now, I thought I had added you to my favorite builder list, I'm embarrassed to discover today I had not, so I apologize for that, will add you as soon as I'm done writing this comment. Now to the creation, I just love it. Glad to see you did not destroy the falcon to build this DC-10 looking plane. I love the third, tail engine, looks so real (nice little german flag too =D). Nice seating arrangement. Words can't describe it, so all I can say is Great Creation, unbelievable, and now I just can't wait for your next one :D
Steffen! You're back! I love this one, The rounded nose is brilliant, and the whole plane in general is just candy for the eyes! I really like the intricate work on the rear of the plane, it really makes it look sleek and smooth. I have something built here: http://www.mocpages.com/moc.php/211722, it was inspired by stuff from you and other builders, I think you'd be impressed, if you don't mind of course. ;). ~T

Wow you've really hit the nail on the head with this one it just looks great loving the interior detail and the engines too everything is just great keep on building :)
Oh my heavens; I can't describe how impressed I am. The cargo hatches, passenger doors, body design, smooth edges . . . the list of my compliments is endless. The front seems a bit awkward to me, but I know I couldn't have done better. How I wish I could be back to working on my NAIA Aeva! Well, maybe someday. Until then, I'm going to keep admiring your ever-outstanding work. It's amazing what you're still able to do despite a new job! Congrats; I love it so very much!
Very nice, probably the most extended minifig scaled airplane I've ever seen, great shape, I love the detail on the wings, only thing I might find less brilliant are the colors, there could be a bit too much red (particulary on the interior) nevertheless, an awesome built, great job !
