Following the Palm 90 crash in Washington DC, I heard someone in
aviation say something to the effect that if you are not airborne within
30-seconds of brake release following throttle up, abort and determine
why you had not reached flying speed.

30 Seconds? I'd be in the shopping center IF I could make it through
the brush and airport fence...and jump the ditch...and through traffic
on a 5-lane road. Even in my 48 year old plane it would have become
blatantly obvious well before 30 seconds.
