ICAO REPORT:
In the ICAO report, the United States has stated that there were no other small civilian aircraft in the area other than the BTTR aircraft and the Cuban interceptor MiGs. In the transcript between the MiGs and the Cuban controllers, the MiGs positively identify the third BTTR aircraft, Just as it had done with the other two aircraft, prior to shooting them down. Yet it is interesting to note that in paragraph 1. 1.47 of the ICAO report, the U.S. accuses Cuba of chasing a non-existing (non-existing because the U.S. agrees that there were no other aircraft in the vicinity) light blue and white Cessna # 337 and Cuba agrees that the Cessna it was chasing was not the third BTTR aircraft. This bizarre explanation adopted by both the Unites States and Cuba appears to be a convenient position for both parties to take, to cover-up the fact the Cuban MiGs crossed the 24th parallel. This position has been beneficial to the United States in contending that its response was only mildly inadequate. It has also been beneficial to the Cubans 'in that it makes the murder of the pilots less egregious. See ICAO report pg. 13 paragraph 1.1.47.
In conclusion, when the U.S. Air Force radar print screens and location data, are cross referenced with the transcripts of the Cuban MiGs with their controllers, both documents concur that the last remaining BTTR aircraft was well to the North of the 24th parallel and that the Cuban MiGs were within 3 minutes of reaching the United States and very close to U.S. shore. This notwithstanding. it is clear that the U.S. response was grossly inadequate, given the full knowledge of the dangerous circumstance.
1.1.47 At 15:31 hours a second pair of Cuban military interceptor was launched to pursue a radar contact east of Havana and north of Bejucal. At 15:40 hours the interceptors were directed to fly north from a position .5 kilometres north of Santa Cruz in pursuit of a radar contact. At 15:45 hours the interceptors reported seeing a light blue and white Cessna 337 but were unable to read the registration. This aircraft was reported to be at an altitude of approximately 2 000 m. At 15:51 hours the interceptors were instructed to discontinue the mission. According to the authorities in Cuba, the reason was that the contact was then outside Cuban territorial airspace and withdrawing to the northeast. United States radar sources indicated that this search was in the area of 23 35N 082 58W, and did not show any radar contact in that area other than the Cuban interceptors. At the time of this Search N2506 was tracking well to the north and was at 15:46 hours according to both the Cuban and the United States radar records, some 40 NM northwest of the Cuban interceptors

TRANSCRIPT OF RADIO CONIMUNICATIONS AS RECORDED
ON BOARD N2506
The tape provided by the Brothers to the Rescue was recorded by the pilot of N2506 on 24 February 1996. The recorder used a microphone in the pilot's headset and thus recorded any radio and intercom communications as selected by the pilot at the time. Apart from the intercom in N2506, the communications were between: the three aircraft and including (lie Brothers to the Rescue Opa Locka hangar, VHF and possibly HF; Havana Centre; USN Key West, and Miami Radio. Various other aircraft appear in the text, these are conducting their routine communications with Havana ACC. The recording was partially in English and partially in Spanish. When the original language was Spanish, a translation into English has been provided and indicated by the use of italics. The United States provided a record of communications between the Brothers to the Rescue aircraft from 15:03 to 15:31 hours
The three Brothers to the Rescue aircraft are identified as:

2.2 Developments in the United States on 23 February 1996
2.2.1 According to authorities in the United States, the "Concilio Cubano, an umbrella human rights organization in Cuba" had been denied permission by the Cuban government to hold a public meeting planned for 24 February 1996; the Brothers to the Rescue had publicly stated their support for the Concilio Cubano and had filed ail application with the Department of Treasury for a licence to send financial assistance to the group.
2.2.2 In the early afternoon of 23 February 1996, the Department of State's Office of Cuban Affairs contacted the FAA's Office of International Aviation (FAA/AIA), to indicate that "because of crackdown against dissidents in Havana the BTTR [Brothers to the Rescue] might attempt a flight to demonstrate solidarity with dissidents and in defiance of the Cuban government during the following day(s)." The Department of State also indicated that "information suggests that the Cubans are in a 'rough mood'.'
2.2.3 The FAA/AIA then sent, at 14:40 hours on 23 February 1996, a message via electronic mail to FSDO, FAA in Miami and to FAA Headquarters, as follows:
"... The Government of Cuba's crackdown on dissidents has resulted in a number of arrests (in Havana) and the cancellation of a meeting that was to have been convened by the umbrella dissident organization 'Concilio Cubano' tomorrow.
We have received a call from the State Department indicating that since Brothers to the Rescue (BTR) and its leader Basulto support and endorse the Concilio Cubano, it would not be unlikely that the 'BTR attempted an unauthorized flight into Cuban airspace tomorrow, in defiance of the GOC and its policies against dissidents. State Department cannot confirm that this will happen and is in touch with local law enforcement agencies to better determine what is the situation, I've reiterated to State that the FAA cannot PREVENT flights such as this potential one, but that we'll alert our folks in case it happens and we'll document it (as best we can) for compliance/enforcement purposes.
State has also indicated that the GOC would be less likely to show restraint (in an unauthorized flight scenario) this time around
FSDO was requested to convey the above message to the military liaison officer at Miami ARTCC.
2.2.4 The military liaison officer received this message at 18:00 hours. He then briefed the Miami ARTCC shift supervisor and military liaison officer on duty of the "potential activity for the following day According to the authorities in the United States: "The specifics of the briefing were that the Miami AIFSS and Opa Locka Tower were to be advised to co-ordinate all flight plans and departure time information with the Watch Supervisor, the Watch Supervisor and/or the Military Liaison Specialist were to track the Brothers to the Rescue transponder codes as long as possible, take detailed notes and advise other facilities (DAICC, NORAD. etc.) of the "activity." The military liaison officer then called DAICC (Customs facility in California) supervisor. briefed him on the potential Brothers to the Rescue activity and requested their assistance. Furthermore, the manager of FSDO in Miami requested that the B94 aerostat radar balloon at Cudjoe Key. Florida. to be "Put up".

2.3 Events on 24 February 1996
2.3.1 Situation in Cuba on 24 February 1996
2.3.1.1. According to the Commander of the Anti-Aircraft Defence and the Air Force of Cuba, 24 February 1996 was a special day, the one, hundred and firs( anniversary of the Cuban War of Independence. There were carnivals and several other large public activities in Havana. The Brothers to the Rescue group had announced support for counter-revolutionary activities, and hence the Commander went to the command centre. At about 09:40 hours flight plan messages were received for flights by the Brothers to the Rescue aircraft. From 10:16 hours three unidentified aircraft violated at various moments Cuban territorial airspace and activated danger areas. No SSR transponder codes were seen on radar for these aircraft. The Commander further stated that he ordered military interceptor aircraft to take-off and to persuade the unidentified aircraft to withdraw, and that when the unidentified aircraft saw the MiGs, they withdrew. Two MiGs stayed north of Havana until the unidentified aircraft retired to the north, and the MiGs returned to base at 11:30 hours. By noon. three new-flight plan messages for flights by the Brothers to the Rescue aircraft were received, and the Commander decided to stay in the command centre.
2.3.1.2 According to the authorities in the United States, their radar did not record any Cuban military aircraft activity, nor any unidentified aircraft, north of Havana between 10:12 and 11:30 hours. According to the authorities in the United States, they had no evidence that any Brothers to the Rescue aircraft departed from the United States in the morning of 24 February 1996. The Brothers to the Rescue confirmed that they had no flights that morning. However, United States radar recorded Cuban military aircraft activity north of Havana between 12:15 and 12:45 hours. According to the authorities in Cuba, no such activity took place at that time.
