following pdf file contains all of the resized Project Blue Book
documents below and is now housed on the NICAP site for security
The original over-sized docs from the Blue Book site are listed below:
The BB memo does say that F-94s were scambled twice. The objects were observed visually from the tower and planes were directed visually but could not make any contact. It specifically says that radar picked up nothing unusual on any of the dates. There is also no mention of a theodolite so I don't know where this comes from in UFODNA mention below.
Page 1 Memo for the Record, mentions many sightings dated 17, 19 and 23 June 1952 and treats them all together.
This is in the NICAP chrono under the date of 17 June 1952:
June 17, 1952; McChord AFB, Wash. (BBU 1298)
Between 7:30 and 10:20 p.m. Many witnesses saw 1-5 large silver yellow objects flying erratically, stop and start. (Berliner)
The Fournet drawing shows 6 objs, not 5, but here's apparenrtly the same case giving "5 or 6".
17 June 1952 19:30
McChord AFB, Washington, USA
Project Blue Book "unidentified" case. Many observers with theodolite. 5-6 fast discs, chased by USAF F-94s. Objects were tracked by radar and sighted visually. More than five yellow discs were observed by several witnesses at an airfield for 170 minutes.
