                                        About the only difference between the HTL-3 and the HTL-2 was the fact that the former, seen
                                        above at the Bell plant in the early 1950s, had single pilot controls versus dual on the HTL-2.
                                        Nine of these training helicopters was acquired by the US Navy and they were later re-classified
                                        H-13D.
