Also from around that time period:
Toward the Unknown - 1956
A lot of great scenes of 1950s fighters and bombers to include the XB-51 as the fictional "Gilbert XF-120"
A Gathering of Eagles - 1963
Like 12 o'clock High, but B-52s and instead of the Luftwaffe, SAC Inspector General is the enemy.
Then of course there is Dr. Strangelove and Bombers B-52
