PanAm 747

Has anyone seen the picture on here with the PanAm 747 with a fifth engine? Can someone tell my why that extra engine is there? Thanks.

The sole purpose was to transport engines (normally within the airline) to another airport where it was needed for maintenance. So instead of chartering a cargo airplane to do this, a few airlines have transported extra engines (not very common though) on their own airplanes; I can't think of anybody still doing this today.

Then engine, which is situated under the wing between the #2 engine and fuselage is being ferried for repairs...The alternative to that is taking the engine with the bad engine and flying that aircraft with the 3 functional engines.

the fifth engine is being ferried between stations, most aircraft can carry spares like this. With the extra engine hanging out there, cruise speed is reduced from M 0.82 to M 0.78. The Air-India 747 destroyed by a bomb in 1985 near the end of it's flight to Heathrow was carrying a fifth engine. The Air-India flight was late as a result of the slower speed and was thereby still in-flight when the device exploded. (The same day a CPAir 747 landed at Vancouver and a bomb exploded as the containers were offloaded - two airport workers died but cos the flight was on time the aircraft was safely on the ground when the timer went off, as was the bombers' presumed intention.)
