The purpose of discussion here is to sift through the B.S, and hopefully get some news.
Analyzing the limited data there is, one aircraft was destroyed. Contrary to your statement, the Landing gears or the vertical stabilizer were not recovered. Ashes to Ashes....Those parts are of no use from an aircraft lost to fire.
For the second and third aircraft (since we have only seen the fourth out till now), its safe to assume that some work is going on, or has been going on.
If we critically think about the nose radome damage theory, that is a bunch of B.S. Changing a nose radome is Child's play for PAF. That means, that the second and third aircraft would have some damage which does not allow PAF to show them in public.
Now lets look back. Three aircraft in a hanger, one burned down completely. Friends, that is a lot of heat in one hanger. If there is so much heat in a hanger, lets assume, like an oven, no wonder the other two aircraft are in hiding...
Whether or not the rumors of repairs on second and third aircraft are true, there must have been some major structural and electronic work on Saab done at Kamra. However, I highly doubt that Kamra has the capability to undertake work on airliner structures. Maybe they can repair the radar, KARF has been doing that for years...but repairing an airliner structure is awfully different from recovering mashaks and F-6s. I am sure there are experts around the world that have this capability, but Kamra is not an MRO for SAAB or regional jets of life and specifically heavy repairs is beyond their expertise.
What do you guys think?
