- The US Air Force Thunderbirds, the Air Force’s Flight Demonstration Team, perform a maneuver called the High Bomb Burst Cross, in which four F-16s cross ove each other at high speed and close proximity.
- One Thunderbird pilot, USAF Maj. Will Graef, filmed the maneuver from inside his cockpit, giving viewers a new perspective on the maneuver.

You may have seen the U.S. Air Force Flight Demonstration Team, The Thunderbirds, perform their thrilling "High Bomb burst Cross" maneuver, but you’ve never seen it like this.
This new video, shot from inside Thunderbird #2, flown by "Left Wing" in the diamond formation, USAF Major Will Graef, provides some sense of the rate of closure of the four aircraft. The speed and proximity of the aircraft truly leaves little margin for error.
The High Bomb Burst Cross is flown during the Thunderbirds’ "high show", when visibility, cloud cover and winds enable the team to fly with their highest maximum altitude restriction. The "Cross" is actually the convergence of the four diamond formation aircraft at the bottom of the High Bomb Burst, a spectacular vertical break when the four F-16s of the diamond formation climb vertically to altitude in the Thunderbird diamond, two aircraft perform quarter-rolls, one performs a half-roll, and the aircraft "break" at somewhere between 12,000-15,000 feet altitude. Following the break, the aircraft diverge in four different directions, performing the back half of a loop to re-converge over show center.

Viewed from the ground the High Bomb Burst Cross looks like the aircraft converge at incredible speed, which they do, but also at very close vertical proximity, which is a bit of a trick of perception as viewed from the ground. But even if the separation distance between the F-16s does appear greater as viewed from the cockpit video camera of Thunderbird #2, Maj. Will Graef’s aircraft, there is still little margin for error in a maneuver when rates of closure are well above 1,000 MPH.
The new video, posted late this week by, Thunderbird #12, Public Affairs Officer Maj. Ray Geoffroy and Thunderbird #2, "Left Wing" in the diamond formation, Maj. Will Graef. Within hours the video had thousands of views and hundreds of shares as one of the most unique and dynamic scenes to surface during the 2019 airshow season so far.
By the way, it’s worth remembering that other demo teams perform a similar maneuver. One these, is the Italian Air Force Frecce Tricolori whose peculiarity is the Downward Bomb Burst, a maneuver which has been part of the Pattuglia’s tradition since its creation, having been part of the Italian Air Force heritage for about 90 years now. During the Downward Bomb Burst the aircraft, starting from a high altitude and in formation, dive towards the ground and then separate into 9 individual elements which depart in different directions, finally returning for an opposition pass, at three different levels, over the same point.
