Re: Chris Gibson - the man behind North Sea Aurora sighting
I think you're mixing Have Blue and Tacit Blue here Abe.

Abraham Gubler said:The Gibson Delta is very unlikely to be an advanced stealth aircraft because of its planform. The 90 degree to the boresight rear is not very stealthy. Any radar with some look up or look down would get very strong returns from this trailing edge unless it was dripping in RAM.

flateric said:Well, remembering Flying Dorito...that have the same trailing edge configuration...that didn't disturb Fort Worth guys so much
Bruce Johnson said:Yes, I suspect that the Quartz program was similar to Have Blue in scope and operation. By around 1980, Have Blue was well over, and the F-117A was in full development. Lockheed wanted to stay out front and take stealth technology to the next level. So, they proposed a flying testbed project to
CFE said:Northrop's "Low-Altitude Penetrator" concept for the ATB would be a good fit for the Gibson sighting, and it would certainly explain why it would be flying with F-111's. Only problem with this explanation is whether the aircraft would match the size of Chris Gibson's mystery plane.
CFE said:Were the F-117's ever deployed abroad when that program was secret? I'd think the risk and security expense of an overseas deployment would rule out the Gibson sighting as a secret US aircraft.
quellish said:Even now, the only things I know of that could match something like that are an AURORA or an "A-17".
In 1989 there were a lot of things flying.... but nothing with that kind of sweep. I do not think Chris would mistake a Dorito for what he describes. There was a cruise missle program that would have looked similar, but would have been much smaller and did not likely produce anything flying.
LowObservable said:The Gibson planform could be a subsonic low-altitude penetrator except for one glaring issue, which is that you're going to get seen from behind and shot in the butt. The question of the rear-aspect signature (how LO you had to be from what angle) had already been crucial in the Have Blue competition, 15 years earlier. On the other hand, something that goes as fast as a lot of missiles doesn't have to worry about a rear-aspect signature.

The planform as presented by Gibson aligns with only one actual, verifiable, real, confirmed, declassified aircraft design: the Northrop ATB low altitude penetrator bomber. ... The pure delta or 'Dorito Chip' planform was the low altitude stealth state of the art of the 1980s. We have two declassified aircraft designs to confirm this (including the A-12A). They don't need to be good or effective designs, they just had to exist.

shockonlip said:The above is important as it indicates the shortcomings of a low altitude penetrator. Indeed,
it also indicates that other designs besides NLAP were looked at. So if they constructed a real
NLAP, it would have been a waste of money and would have taken funds needed for the winning
design.
shockonlip said:but I don't agree on you're dismissing of all other deltas as the Chris Gibson delta, based on just Fig 3.5 in the "B-2 Systems Engineering Case Study".
LowObservable said:You're getting all excited.
LowObservable said:The North Sea sighting could have been all sorts of things. Basically, though, there have been two seriously studied classes of vehicle that look like that: hypersonics and a couple of stealthy low-altitude penetrators.
Abraham Gubler said:Actually in the context of the time of the sighting 1989-90 stealth planforms were just being revealed to the public (November 1988) and certainly the original Northrop ATB low and high altitude penetrator concepts were not public. So I have no problem with someone in 1989-90 thinking that the Gibson Delta could have been a hypersonic. It was probably the best fit for that time, apart from not really having any evidence, including cirumstantial, to support such a conclusion.

If you Google Earth Area 51 there appears to be a lot of evidence of significant activity we haven't heard a peep of.
