Boeing copying other aircraft ?
Just noticed that the new Dreamliner's nose section looks very similar to the comet's nose section.
check them out :-

Just thought i'd share this with everyone.

Actually just to be different the Boeing folk decided to make their's out of plastic so they could not be accused of copying De Havilland.
Well, the Caravelle copied it too

Yeup, must be the design of choice for the fashionable passanger airliner using leading edge fuselage construction and materials 'of their day'
Lets just hope the 78 does not suffer any of the problems associated with the 106.
Still, it looks very smart. Looking forward to seeing the Boeing fly.

I believe Sud Aviation paid a fee to deHavilland to use the Comet nose section design on the Caravelle, under licence. This is not the same as 'copying'.
Boeing copying the alloy nose of the Comet on a 787 nose profile manufactured from molded composites - hardly!
Did they both choose the aerodynamic profile of a bullet profile to minimize the drag and maximize the aesthetic appeal of their respective designs? Probably, but the 21st century molded composite structure of the 787 allowed Boeing to do it with just four transparencies, instead of the ridiculously expensive and heavy eight or ten windows on the Comet, necessitated by the state-of-the-art aluminum structures of the day.

I like the snotter on the 787
But moving off Boeings. Is it just me? I always think the nose on the A318/19 etc looks old,fat, & stubby.
Guess the wind tunnel tells no lies?

Airbus could always do what BAC did to the One Eleven and put a pointy nose cone over the radar as an afterthought. Improved its looks no end!
Never could understand why the Broussard required two vertical fins when one would do??

The second manufacturer had some sheet metal left over to make a second vertical stab, I guess. 
You're right, the 'first' one did have early handling issues and the dorsal was grafted onto a Chippy style fin to stiffen it up directionally. Much simpler than two separate fins and rudders, though!

Don't think Boeing is copying anybody, in fact could they have a patent on it? Everyone copied Boeing perhaps. Boeing 307, first flight 31 December 1938. Utilised B-17 wings and tail feathers. Also the first pressurised airliner.

Re: That dorsal fin... square fuselage would be the problem methinks, shedding woking great vortices, dorsal fin only partial solution.

HM I believe you are correct with your comment about the slab-sided fuselage. The Beaver presented a quirk when taking off on floats with a stiff crosswind. Even with the dock knocker ventral fin, the airplane had a tendency to turn downwind before it got on the step.
