Engine failure in WWII
Hello. I don't know if this is the right place to ask these things. If not, I apologize in advance. I'd like to know if, during the WWII, a twin engine aircraft could fly without an engine.
1) Is it correct that a twin engined aircraft, in normal contitions, has exactly twice the power needed to fly?
2) Could an aircraft like a Vickers Wellington take off and/or fly with one engine out of service?
Thanks in advance.
