burnt toast event
n.— «A lot of it…is what we call “burnt toast” events. They’re like a near miss; you have no idea at the time how serious it is—or could have been. Sometimes it’s minor, other times maintenance teams open up the belly and all of the insulation is charred.» —“When There’s Smoke, There’s Trouble” by Kathleen Bangs Business & Commercial Aviation Mar. 1, 2005.
