Re: Robert M. Edholm - test pilot McDonnell - sound barrier?
Stig,
In an article on the XF-88 in the July 1982 Aeroplane Monthly Bill Gunston wrote that on 12 May 1949 Edholm dove the aircraft from 41,000 ft. and reached a Mach number in the region of 1.17 to 1.19. He goes on to remark that there was not "the slightest buffet, trim change, flutter or yaw".
The XF-88 was an experimental fighter, not a special test aircraft like the Bell X-models.
