This is congruent with the suggestion of Webb et al. [ 34] that the wing morphology of M. tuberculata represents a compromise between different adaptive pressures: i.e. slow, manoeuvrable foraging flight within dense forest, and fast, direct commuting flight between forest patches.
The CityAirbus craft is a vertical take-off and landing craft that uses a four rotor design, and that would be able to take up to four passengers on short flights in dense urban areas, with the aim of connecting major transportation hubs including train stations and airports.
A dense flight plan, physically challenging experiments (including extravehicular activities) and a complimentary set of human factors research experiments offered a unique opportunity to study the impact of a high workload on crew vigilance.
For the first time, the problem appeared to turn deadly April 20 when a small propeller plane carrying four people on an aerial and surveying photography flight smashed into the dense spruce and birch trees near Anchorage.
Padel's own dense style takes flight in the tropics : "Leaves of all textures that a leaf / could be: palm, fluff, prickle, matte and plume; /bobbled; shaggy plush.

So began hours of circling around Gatwick and the South Downs, tracing a dense, bright green circle on flight tracking websites and alerting a small army of planespotters.
Despite their numerical dominance, they are often difficult to observe because of their small size, quick flight speed, and preference for patches of dense vegetation.
The images were acquired with low overlaps (60% along-track, 30% across-track), as the flight was not conceived to generate a dense point cloud.
Some have dropped off the map - they often do just before they undertake a long flight - presumably resting and feeding in dense vegetation.
