In this photo, published in the May 18, 1966, Chronicle, HPD Sgt. J.E. Armstrong holds up a bomb that was unearthed at the San Jacinto Battleground -- proof the Texian Army used an air assault in the decisive battle for Texas independence.

Just kidding. This was believed to be a World War I-era bomb. Armstrong told the newspaper these types of bombs were dropped by hand by pilots around 1917.

A man walking the battleground with a metal detector found the device, which was promptly turned over to Houston police and likely disarmed.

(By the way, does anyone know what building that is in the background?)
