One of the loudest aircraft I've ever flown in was a US Navy owned Lockheed C-130 Hercules which was used as a taxi from Guam to Tinian to transport personnel. Back in August 6, 1985, I was on the USS Puffer (SSN-651) and we had stopped at Guam a few days before and then they asked for volunteers to go to Tinian to represent our ship for a ceremony at Tinian. Most guys onboard were unaware of the significance of August 6 but on that day, on August 6, 1945, the B-29 Superfortress of the 509th bombardment group called Enola Gay dropped the Atomic bomb on Hiroshima, Japan, and it had taken off the island of Tinian on the US Territory of the Northern Marianas. By the way, the world's deepest ocean canyon, The Mariana Trench, is nearby. This version of the aircraft is the newest, the C-130J version. I flew in a C-130B version. The C-130 was first produced in 1953 and 70 years later, it is still in production. That is the longest in world history and the Hercules is so versatile that they simply haven't come up with a better replacement.
