Something I thought most people here would be interested in. In their latest issue (December 2010) Popular mechanics hid a data logging device from National Instruments that would gauge and record vibration, temperature, and orientation. The package was sent on 12 3-day trips from New York City to Santa Monica, CA to Austin, TX.
Some benchmarks: a moderate jostle registered as 2g's, and a 2.5 ft drop as 6g's.
The Results (If I had a scanner, or could find it on their site I'd link that):
USPS handled the package the gentlest, with an average of only 0.5 spikes over 6g's per trip. UPS-2 spikes average, and Fedex 3.
Orientation wise, USPS fared the worst, with an average of 12.5 changes, Fedex 7, UPS 4.
Temperatures always stayed between 47-80 degrees Fahrenheit, with Fedex having the least fluctuation by .79 degrees less shifts on average.
Marking the package as 'Fragile' or with 'This end up' ended with the packages received more abuse than normal.
If you want to read the full article, pick up the latest issue of the magazine, but I figured this would be some data to all give us an idea as to what happens to our packages in the mail.
