A place for majestic STEMLORD peacocking, as well as memes about the realities of working in a lab.

Rules
Letter D is perfect for what's being described thereby: D for "Disaster", "Dying", "Drowning" if the helicopter is flying next to the sea. It could be letter S, too, for "stall", "smashing onto the ground" or, if this acute pitch exerted onto the aircraft was deliberately maneuvered by the pilot themselves, a seven-letter word starting with the letter S.
