Raven O-1 Aircraft


Tail Number Listing


This table is a compilation of information concerning the Cessna O-1 "Birddog" aircraft flown by the RAVEN "in-country" forward  air controllers  from 1964 to 1973 in the Kingdom of Laos. The information was compiled from previously researched material combined with inputs from the RAVENs themselves. This project is a work in progress.
Project initiated on 01 October 2004. Last update 25 March 2008
Explanations

Black entries are information from the referenced source. Red entries represent my expansion of the initial source information using other source data. Dates in the Who and Entered fields are computer dates without the century (year, month, day). Usually aircraft were referred to by the last three or four digits of the serial number. The bold red shows the association to the serial number. C/n is the Cessna construction number. Question marks indicate the information is probably true but unconfirmed. WFU = whereabouts, fate unknown. AAM = Air America

A comment on sources: 
  • Dr Joe Leeker  researched  O-1 aircraft as part of his work on Air America (AAM) aircraft. This excellent research is archived at University of Texas, Dallas and is on line as part of their Air America holdings. http://www.utdallas.edu/library/special/aviation/AirAmerica  All Leeker research is used with permission of Dr Erik Carlson, University of Texas, Dallas
  • Although AAM did not operate O-1s as part of their fleet, they performed maintenance on Raven aircraft at their Udorn facility regularly after 1968. A key data point was the April 1972 maintenance summary that listed the active aircraft. Ravens Larry Sanborn and Ed Gunter provided additional information to Dr. Leeker.
  •  O-1 serials are part of my Secret War research having flown backseat in several O-1s out of Savannakhet in 1968-1969.
  • In October 2004, I requested assistance from the Ravens in sending me the serials of the aircraft they flew during their tours in Laos. Responses are included.
  • Additional research has revealed a few additional serials
