I don't want Excel to save the file as a .xltm file, rather I want it to save the file as a .xlsm file. However, if I put the .xlsm file extension in the file name, it does not like that and it gives me an error.
The F-35 Lightning II is the U.S. military's next-generation fighter jet, billed as the most advanced warplane of its type yet developed. The single-seat, single-engine aircraft features advanced stealth capabilities, combined with improved avionics and sensors. The F-35 has a maximum speed of Mach 1.6, which is 1.6 times the speed of sound, or about 1,200 mph (1,930 km/h).
The Sukhol Su-27 is a twin-engine fighter plane built by the former U.S.S.R., in an attempt to outdo similarly advanced American aircraft. The plane made its first flight in May 1977, and officially entered service with the Soviet Air Force in 1985. The aircraft can reach a maximum supersonic speed of Mach 2.35 (1,550 mph, or 2,500 km/h), which is 2.35 times the speed of sound. The Su-27 earned a reputation of being one of the most capable fighters of its time, and some remain in military use in Russia, Belarus and the Ukraine.
