Where was Mercury Freedom 7 launched?

It was launched at Cape Canaveral, Florida, on May 5, 1961 (9:34 EST).

The Freedom 7 capsule was used by Alan Shepard on the first US manned space mission, a 15-minute suborbital flight called Mercury Redstone 3. The rocket used variants of the Redstone and Jupiter-C ICBM boosters (for later Mercury missions, the Atlas missile was used).
