I wouldn't trust it anyway. Saw a line of palm trees go up when the APU restarted with a 'spit' of about 150 feet on the next door A/C. Fire brigade came over to the two MD types to figure out who did the fiery deed.
My MD87's right cowl was clean, reasonably soot free. The 717 alongside was missing paint and soot from their cowl.
