An excellent, recent close-up photo of a section of Area 51 just
appeared on Roadrunners Internationale website.   It shows the The Red
Hat hangars at Area 51.
The slightly-angled satellite photo (that seems to have taken from a
northwesterly direction, i.e., facing southeast) shows 3 white aircraft
parked right in front of Hangar 4.  It also shows Hangar 3 (to the left
of Hangar 4).  It also shows Hangar 5 (next to and south of Hangar 4).
It also shows Hangar 2 (left of Hangar 5 and next to and south of
Hangar 3.
Could one of the 3 white aircraft (the largest one) be B58?
You can see the photo towards the bottom of the front page of
www.roadrunnersinternationale.com, one of the 3 best and most extensive
websites on Area 51, the other two being www.dreamlandresort.com  and
