Does anyone know about Boeing LRA?

Looks like the 1978 Boeing 777-100 Trijet, a concept that preceded ETOPS. LRA likely is for Long Range Aircraft, which is what the 777-100 was designed for as a transoceanic aircraft.

Better answer than mine. Thanks.

Well, not exactly, the first picture by IKPJH;PHLO looks more like a T-tail, because I don't see the lower horizontal stabilizer configuration. Possible this version below of the 777-100. However, I'm not convinced that this is the same aircraft. The inlet on the center engine looks shorter on the LRA aircraft.

Definitely agree on the T-tail. The underwing engines also look really far outboard compared to the 777-100 trijet iterations we have already posted. It's definitely a weird one.

From another perspective, the Boeing LRA does not have a T-tail

My first thought was Large Regional Aircraft, NMA probably isn't the only time Boeing's considered a regional twin aisle.

I think the Boeing LRA looks like this,
PS; I don’t know whether the Boeing LRA’s tail is a traditional one or a T-tail, so I made both versions.

Hmmmmm... I wonder what the 747-type aircraft on the top right of that image might be, it has to be some kind of proposal, and is quite massive, seemingly bigger than almost any other 747-type concept I've seen before, so perhaps you could try to make a design for that in the future like you just did the Boeing LRA earlier this week. :)
 
Very close, but if you look very, VERY closely at the top right of that image I quoted on earlier, that plane seemed to have just a hump deck, and not to mention that its entire designation seems to use Boeing's signature font, whereas the one you just linked to me has the "DOUBLE DECKER" part in a more casual font.

Now moving to something unrelated, have you seen this triple decker proposal by British Airways from 1992?
