Answer:
Boeing has produced many different airplanes. Most current ones are in the 700s line (Boeing 707, 717, 727, 737, 747, 757, 767, 777, and 787). Each number has many different models and setups, as the number just specifies a general fuselage design. Some additional models are considered part of the McDonnell Douglas company, as they were built before becoming a part of Boeing.
