Several years ago, I flew to OSH
with some friends. We departed GRR
, climbed to 13,000', and crossed over Lake Michigan (Despite an uneventful flight, it's something I'll never repeat in a single-engine airplane...the engine tends to make some awfully strange noises out toward the middle of the lake).
Upon reaching FL130, I went to grab my small bag of potato chips, and was alarmed to notice that the bag was bulging and ready to burst. I carefully depressurized the bag, and luckily avoided a potentially hazardous uncontained chip explosion.
It was a close call....
