    Topspeed has a dream! We should not put him down for it. We can’t just point out the inefficiencies of his train of thought when they occur. You can rest assured that as he finds out more and more about aircraft design, his plane will get bigger and bigger.

    Indeed that has been happening. :eagerness:

    Smaller than TARANIS ( volumetrically ) !

    Similar sized engine(s); http://en.wikipedia.org/wiki/Rolls-Royce_Turbomeca_Adour

    Wow, how could we have missed it, your munchkin mobile has no landing gear.

    An Me-163 wannabe, and probably as effective also.

    No gear has been there all along..scroll few pages back !

    I have a couple of Swiss (German) friends, and they are the most anti-military people I know! 🙂

    J-31 added !

    Yes, … simply due to their overall lower production rate and even more contractual issues, since they were ordered for each seperate year and not as a whole block.

    By the way why do You still show the J-20 in that size ??? We all know (at least should know) that it is only a bit shorter than a Flanker.

    Deino

    I don’t show anything here…just added my G-1 with a ready made list that had a Shinshin ( ATX-D ).

    You can see above the right size with a Flanker.

    ——

    edit; here is the renewed list ! I took 9% off the size on displayed J-20 !

    I heard japanese planes are more expensive than the western ones. Is this correct ?

    Thats a BWB wing and its not a bomber design, think civilian transport configuration first, possible airlifter configuration second. No Bomber.

    I prefer this view that converge more with what we see in front of the leading edge :rolleyes:

    It is obviously no longer flying since its cockpit canopy was for sale 4 years ago.

    I was able to find F-35 3-views and scale them in the same scale with few smaller fighters.

    There are two sightings by different people, take a look here:

    http://theaviationist.com/2014/04/23/two-different-black-projects/

    No one is saying the images are photoshopped.

    Right..text says 3 planes flew in formation…how come I only see one in Texas ?

    The air has more than enough density at 4000m (13,000 feet) to support the weight of the aircraft and it’s load.

    The issue with aircraft used for jumping is keeping increased minimum airspeed in check (when people are holding on from outside) and keeping check on where the weight of all those moving skydivers is going (the jumpers need awareness on this as well). Combine the two (I’ll use a Cessna C208 B as an example) together and it can get out of the pilots control quite easily.

    I’m getting off of the topic now as it looks like the main door was closed in this incident. I am a skydiver, so I am trying to use my experiences and understanding to and get some insight across on how skydiving operations work and how we and aircraft interact. :). It has been a bad year for the sport in general world wide :(.

    I agree. Here is a tail wheeler version; http://www.airliners.net/photo/Aerocomp-Comp-Air/1005244/M/

    What is the speed normally when they jump from C208B ?

    I find it funny and slightly odd that some people on various forums are really unwilling to see this as a new aircraft type.

    To my mind its not a B2, it doesn’t look like a B2 and try as hard as you might with as many filters as possible neither this latest aircraft or the Texas one have the same trailing edge arrangement as the B2 nor are they the same shape.

    And yet people of some distinction are saying its a B2 (which makes me suspicious).

    Neither of the pictures are PSed either (they have been rigorously checked. The question is, what is it and what does it do?

    Personally I think its in service rather than a prototype and I am am prepared to go with the jammer option rather than the LO transport option.

    It is the same image on both…someone claimed there are various sightings…

    Right…someone says he hates trolls…does that make him running an UFO site any more believable ?

    He’s on Facebook, you can send him a message. He may or may not reply. But remember he only reached around Mach 1, ram rise isn’t that much. At 40,000 feet and Mach 0.85 the skin temperature (TAT) is around – 10°C, the actual temperature (SAT) is about – 50°C

    I read he reached mach 1.24.

    I did ask him…thanks.

    Let’s just be careful with what the media says. When skydiving makes the news in a negative fashion here in the UK, it is over sensationalised. Sadly it isn’t a sport known about, or understood, by those out side of it.

    The aircraft (that specific model, or the type in general I am not yet sure of) was operated as a ‘jump ship’ for 14 years or so. That is a long time of cycles, people hanging off of the side of it, high speed airflow entering and circulating in the cabin (assuming there is no use of an internal or external wind deflector). That MIGHT give some backing to be overloaded and one bit of fatigue too much. As for points 2 and 3, I don’t share the opinion myself. The human body will perform worse at higher altitude ( up to 15000 feet as an example) than a aircraft wing.

    Let’s see what the reports say and what the survives say. Thankfully(?) POV cameras are widely used in the skydiving community, so there is a good chance of internal footage as well. I have huge sympathy for those that have to watch that footage….

    BSBD to those unfortunate soles 🙁

    Certainly we must be careful. It was only 6 months ago when 11 people died in similar accident with Pilatus PC-6 in Belgium.

    LIFT that keep the aircraft airborne is defined as this L = ½xPxV^2xAxCl ….so the altitude ( pressure ) is vital and related to the indicated air speed.
