Wednesday, April 17 was a special day for B-25 lovers in Pierre, South Dakota. “Miss Mitchell” paid a visit to the community on a tour of South Dakota to commemorate the Doolittle Raid, in which the B-25 played an iconic role.

The weather may have delayed the planned 12:00 takeoff, but that just meant the B-25 got to stick around a little longer. When it did come time for her to go, the crew decided to do something special for the crowds.

They opted for a ‘hot bottle’ start – instead of cranking the engines over with a modern power unit, they turned the props by hand and then cranked them over in one massive explosion to ignite the engines.

The scene was reminiscent of the takeoffs aboard the USS Hornet on April 18, 1942, 77 years ago. The crew stood by, ready for any fire mishaps.

“Miss Mitchell” dips her nose for a moment, a gesture that shows the power of the 1,700 horsepower Wright Cyclone engines getting ready to show off. Their sound seems pretty similar to that of a Harley Davidson.

Then it’s off she goes! Unlike the doomed Mitchells of the Doolittle raid who mostly crash landed through no fault of their own or their pilots (forced to fly further with insufficient fuel), this beauty gets to enjoy her trip…and so do we!

WWII B-25 'Miss Mitchell' takes off from PIRVintage 'hot bottle start' and a familiar 'gallop' sound on the rampThe crew of 'Miss Mitchell', a World War II era B-25 Mitchell bomber, sure know how to put on a show!Weather delayed the planned 12 noon Wednesday take off, but a group of spectators stuck it out to the end for one reason - everyone wanted to hear the B-25's legendary sound.So the crew gave them a little something extra before leaving. Rather than crank the engines over with a modern power unit, the team elected for a 'hot bottle' start; turning the props back by hand and then cranking them over in one massive explosion to ignite the engines.Pierre ACFR firefighters were on hand with the 'hot bottle' in the event of a fire, just as crews aboard the USS Hornet had done for the original Doolittle Raiders taking off for Tokyo 77 years ago.The nose of the aircraft made a noticeable 'dip' as the right engine caught, indicating the tremendous power each of the 1,700 horse power Wright Cyclone engines could produce on command.Those same engines give the B-25 a distinctive 'gallop' which many compare to the sound of a Harley Davidson.But as the B-25 taxied to the end of the runway and powered up for flight, the gallop faded and the roar of 3,400 horsepower lifted Miss Mitchell into the air.A great day for the Capital City!
