Flashbulb memory/ Challenger disaster

[Anonymous]

My office mate vauguely recalls seeing a study comparing the vividness of remembered 
details recorded immediately after the Challenger disaster in '85 compared with 
memories recorded three years later in the same group of undergraduates.  I did a 
brief PSYC INFO search with little result.  Does anybody have a reference for such a 
study or one similar to that, or do I have to suggest to my colleague that his own 
memory of this study is suspect?
