In a previous incarnation the Phantom Dive had spooked the Gloster Meteor T.7 from the early 1950s onwards. In this instance, turbulence from the airbrakes created loss of rudder and elevator effectiveness at high angles of attack, leading to a sudden undemanded roll and dive.
Hands across the water: more than 220 examples of the T-45 Goshawk have been built by a partnership of BAE Systems in the UK and McDonnell Douglas (now part of Boeing) in the USA.
Before ... an early VTX-TS demonstrator in flight before the introduction of the ingenious tailplane vane. The US Navy declared the navalised Hawk the winner of the VTX-TS competition in November 1981, on the basis of its superb flying qualities, design maturity and excellent fuel consumption.
... and after - note the tailplane vane fitted to the first pre-production T-45A, BuNo 162787, seen here on its rollout from the Douglas plant at Long Beach, California, on March 16, 1988. The aircraft made its maiden flight exactly one month later and the type remains in service today, operating from NAS Kingsville in Texas and NAS Meridian, Mississippi.
McDonnell Douglas F-4 Phantom II in the late 1950s experienced tailplane stall at low speeds on take-off and approach when the relatively small-area, thin-sectioned all-flying tailplane could not cope aerodynamically with the downloads it generated. The solution was to install a fixed leading-edge slat on the tailplane itself
