Imagine a scenario where a routine flight suddenly turns into a terrifying ordeal, leaving passengers injured and experts baffled. This is exactly what happened when an Airbus A320 aircraft experienced a dramatic altitude drop during a Mexico-US flight, sparking a global recall of half the company's fleet. But here's where it gets controversial: Airbus claims the incident was caused by a powerful solar flare damaging the flight software, while space weather experts are scratching their heads, questioning this theory. Could this be a case of space weather gone rogue, or is there more to the story than meets the eye?
On October 30, an A320 aircraft unexpectedly lost altitude, resulting in injuries to 15 passengers. In a statement issued on November 28, Airbus attributed the incident to 'intense solar radiation' damaging the flight software. However, this explanation has raised more questions than answers. And this is the part most people miss: while it's true that intense cosmic radiation can cause 'single-event upsets'—errors that corrupt data—experts found no significant solar activity on October 30 that could explain the incident.
Dibyendu Nandi, a leading space weather expert at CESSI and Professor at IISER Kolkata, pointed out that there was no major space weather event recorded on that day. He suggested that if all other possibilities have been ruled out, the cause might be cumulative space weather impacts or an extremely rare energetic particle event from galactic sources. But even this interpretation remains speculative, leaving room for debate.
Solar storms, driven by the Sun's 11-year activity cycle, can release massive amounts of charged particles and energy into the Solar System. During these events, high-energy particles can strike aircraft electronics, potentially corrupting data or causing system malfunctions. However, flight software is designed to detect and correct such disruptions, raising questions about why this incident occurred.
Here’s where it gets even more intriguing: Prasad Subramanian from IISER Pune explained that while solar flares can flip binary digits (0s and 1s) in electronic systems, leading to catastrophic failures,
