Regards the cutting holes in the fuselage---

Martin H. was asked about the holes, and his remarks were immediate.

Martin's most interesting comment was that the frequency of the tail cone is
changed when you add or subtract material in that area and that people who make these changes without conducting flutter analysis are asking for trouble. 
One high speed pass and a wing over is not a test program.  
 

One last comment, do you recall a recent service bulletin that talked about fasteners on the fuselage access panel?  It seems some have gone to Hinges and dzus fasteners and other devices that do not carry the load.  The company was  saying that this panel is structure and should be attached as structure.
