Ike was known to have flown Piper Cubs and Taylorcraft during WWII, believe he got a civil license but don't know for a fact that he flew as PIC while President, thoughthere is no reason he could not have.
The original post also had the question offirst air to air shots fired. I presume that is projectiles of some kind fired from oneairborne vehicle at another, not photographs. I beleiev it could have been at Vicksburg Mississipi during the Civil War when Union (contract) balloon pilots/observers were callingand correcting artillery fire and a Confederate balloon was launched with an armed crew to shoot the Union balloon down.
