Surely, one of the most famous of Boeing's finest was N601BN... a singularly famous B-747 Model -100 operated by Braniff Airlines. N601BN, nicknamed "The Great Pumpkin", "Big Orange," or "Fat Albert" due to its bright orange paint scheme which covered the giant aircraft from nose to tail, was the 100th 747 to roll of the Everett line and was delivered new to the company on December 28, 1970.
"During the first two weeks in January the company sent the N601BN on a publicity tour covering 17 cities. These flights were meet with great public interest with one particular stop in Memphis attracting 10,000 people to the airport just to see "The Great Pumpkin." This was all in preparation for the inaugural flight from Dallas to Honolulu and back to Dallas.
This lone aircraft flew the route (beginning in January 1971) daily for the next 7 years and one month, accumulating a record 15.5 hours of flight time each 24 hour period.
Uniquely designed maintenance was done on the aircraft during a 2 hour lay over in HNL and was approved in lieu of maintenance usually done over a longer period of time.
To my knowledge, the aircraft flew more hours than anyother B-747...
