    Operation Dragoon (initially Operation Anvil) was the code name for the landing operation of the Allied invasion of Provence (Southern France) on 15 August 1944. Although initially designed to be executed in conjunction with Operation Overlord, the June 1944 Allied landing in Normandy, a lack of available resources led to a cancellation of the second landing.

    Cropped delta – tip is cut off. This helps maintain lift outboard and reduce wingtip flow separation (stalling) at high angles of attack. Most deltas are cropped to at least some degree. In the compound delta, double delta or cranked arrow, the leading edge is not straight. Typically the inboard section has increased sweepback, creating a ...

    In this case the lowest required delta-v, to reach 100 km altitude, is about 1.4 km/s. Moving slower, with less free-fall, would require more delta-v. [citation needed] Compare this with orbital spaceflights: a low Earth orbit (LEO), with an altitude of about 300 km, needs a speed around 7.7 km/s, requiring a delta-v of about 9.2 km/s.
