This comic depicts a situation involving multiple pieces of infrastructure: a ship, sailing towards icebergs, which is tethered to an airship flying next to a power plant towards a bridge. Each of these are labelled with details that clearly reference famous disasters, all which were caused (at least in part) by design failures. All of these incidents are common case studies for engineers studying how things can go very wrong. The implication is that, by putting them all together, most engineers would be highly concerned with the potential for catastrophe.  


- "Unsinkable Ocean Liner" refers to the RMS ''{{w|Titanic}}''.

The ''Titanic'' was a British ocean liner which famously {{w|Sinking of the Titanic|sank}} on its maiden voyage in 1912. It was the largest ship in operation at the time, and was called "unsinkable" due to its size and much-lauded design features. The ship struck an iceberg on the fourth day of its first voyage, breaching the hull and ultimately causing it to sink, resulting in 1,496 deaths. Multiple design inadequacies, including too few life boats and inadequate steering ability, were afterwards identified as contributing to the ship sinking and to the high loss of life.


- "Hydrogen-filled [Airship]" refers to the {{w|Hindenburg Disaster}}.

The {{w|LZ 129 Hindenburg|''Hindenburg''}} was a German airship which used hydrogen as a lifting gas. In 1937, during a landing in New Jersey, the ship caught fire and the inflammable hydrogen quickly ignited, causing the ship to crash and resulting in 36 deaths. While the origins of the fire are still debated, the dangers of using large amounts of inflammable gas in airships were made dramatically clear. 

Ironically, the hydrogen airship appears to have been commissioned for the purpose of mitigating iceberg risks, unless 'iceberg spotting' is for the purpose of steering the 'Unsinkable Ocean Liner' into icebergs.


- "Soviet Era Nuclear Reactor Undergoing a Turbine Test" refers to the {{w|Chernobyl Disaster}}.

The {{w|Chernobyl Nuclear Power Plant}} is located near the city of Pripyat, in Ukraine under the Soviet Union. On 26 April 1986, a reactor core partially melted during a turbine test. This led to an explosion, causing a massive release of radiation. This incident remains the worst nuclear accident to date. The number of fatalities from the disaster are difficult to calculate; two people died from the initial damage, twenty-eight more from acute radiation sickness, and fifteen people who were directly exposed developed terminal thyroid cancer. The radiation, however, spread far beyond the plant itself and the number of premature deaths ultimately attributable to subsequent exposure can't be calculated directly, though most estimates are easily in the thousands.


- "Bridge Prone to Aeroelastic Flutter in High Winds" refers to the {{w|Tacoma Narrows Bridge (1940)|Tacoma Narrows Bridge}}.

The Tacoma Narrows Bridge, a suspension bridge in the U.S. state of Washington, was initially built in 1940. From the time of its construction, the bridge was observed to sway and {{w|Aeroelasticity#Flutter|flutter}} in high winds. About four months after opening, the bridge fluttered so violently in 40 mile-per-hour (64 km/h) winds that it collapsed into the strait. There were no human fatalities, though several people were injured. This collapse is frequently used to demonstrate the dangers of harmonic vibration in infrastructure, particularly structures exposed to strong winds. The bridge was eventually rebuilt, with a redesign intended to prevent such fluttering. 


- The title text refers to the {{w|Space Shuttle Challenger Disaster}}.

The {{w|Space Shuttle Challenger|''Challenger''}} was an American space shuttle which broke up shortly after its launch in 1986, killing all seven crew members aboard before reaching orbit. The disaster was caused by a failure of O-ring seals on one of the shuttle's rocket boosters and the subsequent leak of hot gasses. The likely cause of these failures was because the weather was much colder than normal in the launch area, causing the seals to be well below their design temperature range in the immediate lead-up to being exposed to launch conditions, and were then unable to maintain their integrity. Engineers for the company that had built the boosters raised this concern and recommended postponing the launch, but were overruled.
