Are you sure it was an emergency? Large (and around here sometimes not-so-large <g>

back yards are a common enough landing spot for us. Sometimes, however, a neighbor, trying to be helpful, sees the large flame emanating from the burner and calls the fire department to report a balloon 'emergency' or a balloon 'crashing' or 'in trouble' which is rarely if ever the case. To the uninitiated, balloon landings (and their locations) can cause the whole thing to appear like a 'crash'.
