----------------------------Original message---------------------------- I'm trying to get an address (if firm still exists) or info as to who might have indexes to flights (if it doesn't) for Delta Aerial Surveys. I looked on APSRS cd and didn't locate (as a contributor). We have some frames from a 6/79 flight of area apparently near Thornton CA ("New Hope Project ... DAS job #4593"). I'd appreciate any light anyone might be able to shed. Mary L. Larsgaard, Map & Imagery Lab, Library, UCSB ([log in to unmask])
