Use of diverted engine thrust to provide stable attitude control of a short-or-vertical takeoff and landing aircraft below conventional winged flight speeds, such ...
History of email. The history of email entails an evolving set of technologies and standards that culminated in the email systems in use today. [1] Computer-based messaging between users of the same system became possible following the advent of time-sharing in the early 1960s, with a notable implementation by MIT 's CTSS project in 1965.
