Liquid Hydrogen is not a lot of fun. Anything with an 700:1 expansion ratio is a stored energy hazard in and of itself, but because it's cryogenic it also means the cumulative daily loses in tanks where cooling is not actively maintained will be a constant annoyance. They seem intentionally coy about how the 523 miles where flown, seemingly just above Marina, CA. They have requested that flight tracking not be publicly shown on flight aware.

You might be able to find them on ADS-B Exchange, either live or in the historical data sets. They are somewhat famous for only using citizen-sourced ADS-B data and refusing all requests to delist or hide data (allegedly anyway). It looks like their tail number is N542B but I'm not sure how to translate that to the ICAO hex codes that they use to archive their data nor exactly what date and location the flight took place. Some more sleuthing would be required. https://www.adsbexchange.com/products/historical-data/ https://www.adsbexchange.com/products/historical-data/

  N542BJ is the tail number (not N542B,) flightradar24 has the Mode S code listed even though the flight data is locked there. https://www.flightradar24.com/data/aircraft/n542bj# https://www.flightradar24.com/data/aircraft/n542bj# Some test flights around 6/23 - 6/27. Looks like a pretty boring way to get 523 miles. They should fly the loops over the Indianapolis Speedway instead. https://globe.adsbexchange.com/?icao=a6df7c&lat=36.689&lon=-121.763&zoom=15.0&showTrace=2024-06-24 https://globe.adsbexchange.com/?icao=a6df7c&lat=36.689&lon=-... https://globe.adsbexchange.com/?icao=a6df7c&lat=36.689&lon=-121.763&zoom=15.0&showTrace=2024-06-27 https://globe.adsbexchange.com/?icao=a6df7c&lat=36.689&lon=-...

I wonder if the the high-pressure, non-cryogenic hydrogen tanks used in some cars and buses would work. That technology seems to have solved the major issues, although I suppose aircraft crashes could introduce some additional problems. Toyota has some detail about their system, which is similar to systems used by Honda and Hyundai, at: https://www.toyota-europe.com/news/2015/hydrogen-is-that-safe https://www.toyota-europe.com/news/2015/hydrogen-is-that-saf...

The Hydrogen in our supply chain also comes from petroleum so it’s more dangerous, more expensive and less green than any other alternative. Its would literally be more green to burn coal.
