De727ups, UPS 300s are not different than the passenger ones (or the Fedex )
In fact, the same light is also present next to the handle that allow you to open the forward or the aft. lower bellies.
In the above accident, F/A have been hurt/killed, because they were the first to open a door.
Would a ground handler have opened a elly door without checking the door, he would have been killed by the door popping as a Champagne bottle!!
Message to the 300/310 s F/A: Please, have a quick look at this light before opening.
