Traduction de «its engines just before take-off and cut them just after » (Anglais → Français) :

An aircraft using Taxibot would be able to start its engines just before take-off and cut them just after landing.
Un aéronef utilisant Taxibot serait en mesure de ne démarrer ses moteurs qu'immédiatement avant le décollage et de les couper juste après l'atterrissage.

It is just going up and being unveiled. Just imagine those large Lancaster and Halifax bombers, with the four big engines as they were taking off; and the last bit of land they would have seen before they went off on their mission.
Imaginez le décollage de ces gros bombardiers Lancaster et Halifax, dotés de gros quadrimoteurs.
