Washington, D. C. 20535 Dear Mr. Kelly: January 25, 1974 Thank you for the recent copy of the extortion note in the Trans World Airlines aircraft bombing case. It is my understanding other communications from the offender were received by telephone and transcribed in the offender's jn words, Would it be possible to have copies of those phone messages that dealt with such matters as the locations tof explosives, leasing and dispatch of STOL aircraft, etc.? Undoubtedly valuable psycholinguistic clues would be. involved in these instructions, were tape recorded? Is it possible any of these calls I appreciate this opportunity for informal association.
