The Von Braun Ferry Rocket was a concept design for a shuttle spacecraft developed by Wernher von Braun in the early 1950s.

a' propos..

Starting a nuclear reactor. The blue glow emitted by the reactor is the Cherenkov radiation. Named after named Soviet scientist and Nobel Prize winner Pavel Cherenkov, the electromagnetic radiation is emitted when a charged particle (such as an electron) moves through a dielectric medium faster than the phase velocity of light in that medium. https://www.nuclear-power.net/nuclear-power/reactor-physics/atomic-nuclear-physics/fundamental-particles/beta-particle/cherenkov-radiation/

This post discusses the details of an abandoned hostage rescue plan, called Operation Credible Sport, to extract the Americans held during the Iran Hostage crisis. The plan involved modifying a C-130 Hercules airplane with the addition of numerous rockets, to create the largest short takeoff and landing plane in existence, which would then land inside a soccer stadium near the U.S. Embassy in Tehran. Delta Force operators would then extract the hostages, and the plane would take off from inside the stadium and land on a nearby aircraft carrier.
First, the good stuff - a GIF of the modified plane in action: https://pfmrc.eu/applications/core/interface/js/spacer.png





The plan was to take three C-130 Hercules cargo planes, and heavily modify them, specifically by adding 30 rockets mounted in various spots all over the fuselage, wings, and tail. This modification was an enhanced version of something called RATO (Rocket-Assisted Take Off), and it would enable them to take off and land the enormous planes near-vertically. The plan was to land inside Amjadiyeh Stadium across the street from the US Embassy in Iran, storm the embassy with Delta Force operators, extract the hostages, and then take off from within the stadium. From there, the modified C-130 would land on an aircraft carrier. https://www.homemadetools.net/forum/operation-credible-sport-c-130s-modified-rockets-hostage-rescue-56564#post83923
The planes were carefully tested out, and performed surprisingly well, immediately breaking various aviation records for short takeoffs and landings. One of them suffered a catastrophic fire during testing, preserved for history in the following GIF:

To jest właśnie cała tajemnica tego materiału* który podobnie jak grafit mając bardzo małą przewodność właściwą przewodzi ciepło tylko w konkretnym kierunku (z jednej strony grzejesz cienką płytkę grafitu palnikiem acetylenowym, a z drugiej trzymasz palec !)

Temperatura spodniego pokrycia promu może wahać się od -110 aż do 1500 stopni Celsjusza. Ponadto pokrycie musi wytrzymać również inne warunki pogodowe w tym np. wilgoć. Podczas tej prezentacji na filmie, płytka została podgrzana do 1200 stopni Celsjusza. Złapał ją za rogi gdyż one najszybciej ostygły.
