The Delta IV Heavy (Delta 9250H) was an expendable heavy-lift launch vehicle, the largest type of the Delta IV family. It was the world's third highest-capacity launch vehicle in operation at the time of its retirement in 2024, behind NASA 's Space Launch System and SpaceX 's Falcon Heavy and closely followed by CASC 's Long March 5 .
As of October 2018, only the Delta IV remains in production. Single-stick versions of Delta IV was retired by United Launch Alliance (ULA) in 2019 and replaced by the ULA Atlas V, leaving the Delta IV Heavy the only remaining operational member of the Delta family, flying US national security missions.
It is tide dominated in nature with a tide dominated delta having single channel and is surrounded by an area of 60.8 square kilometres (23 sq mi) covered with mangroves. [4] The river has a catchment area of 8,280 square kilometres (3,197 sq mi) [5] The catchment is wedged between the Goomadeer River catchment to the west, the Blyth River ...
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 ...
Autoland systems were designed to make landing possible in visibility too poor to permit any form of visual landing, although they can be used at any level of visibility. . They are usually used when visibility is less than 600 meters runway visual range and/or in adverse weather conditions, although limitations do apply for most aircraft—for example, for a Boeing 747-400 the limitations are ...

American Airlines is a major airline in the United States headquartered in Fort Worth, Texas, within the Dallas–Fort Worth metroplex.It is the largest airline in the world when measured by scheduled passengers carried, revenue passenger mile, and daily flights.
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.
