I found this photo while browsing NASA/GRC site. I have no other information about this photo other than the caption which accompanies it. I have never before seen any reference to the thrust reverser tests which this photo and its caption indicates by implication. There is no visible serial or other number, the aircraft appears to be well used, and I conclude from its features that it is a C-model. If you know of any information about this photo or the thurst reverser tests, please contact me by email.
The caption with the photo states:
Date Archived: 12/29/1954
Title: F-84 airplane with jet thrust reverser
