Trident help
The DH Trident was capable of incredible rates of descent, aided by in-flight reverse thrust on the outer engines. But I remember hearing somewhere that it also had a facility to use the main gear as an airbrake – mains only deployed, and the gear doors closed afterwards (they were left in the open position when the gear was lowered conventionally for landing). Can anyone confirm this? If true, was there a speed limit to allow the gear doors to cycle?
