The stealth features, similar to those used on advanced fighter jets and bombers, help explain how two of the helicopters sped undetected through Pakistani air defenses before reaching the Bin Laden compound in Abbottabad.
JUST in front of me, a skier jumped from a helicopter and sped down the treacherous slope, zigzagging wildly as he dodged boulders and soared over moguls.
It represents a configuration offering the greatest promise for intercity air transportation, combining the utility of the helicopter with speeds approaching that of turboprop transports.
The completed film features a holdover from the Monty Norman-supervised Dr. No music; the post-rocket-launch music from Dr. No is played in From Russia with Love during the helicopter and speed-boat attacks.
For the last quarter of the movie, Maibaum added two chase scenes, with a helicopter and speed-boats, and changed the location of Bond and Klebb's battle from Paris to Venice.
His Sea Shepherd society, with its fleet of vessels, helicopters and speed boats, acts as a vigilante group, on a mission to fuck up whaling ships by any means possible – throwing stink bombs was a personal favourite – while staying (mostly) on the right side of the law (they've also been pilloried in an episode of South Park). .

Thus caution must be exercised in applying linear acoustic theory to high speed helicopter impulsive noise problems.
The problem of control law design for a small scale quadrotor helicopter enabling both speed and pitch control is considered.
Hybrid vehicles such as the Bell XV-15 tilt-rotor already combine the vertical and hover capabilities of the helicopter with the speed and efficiency of the airplane.
