A swarm of honey bees found hanging from the exhaust nozzle of an F-22 Raptor stealth jet’s engine.

On Jun. 11, 192nd Fighter Wing Aircraft Maintainers found something weird during post-flight operations checks at Joint Base Langley-Eustis, Virginia: a swarm of honey bees hanging from the exhaust nozzle of an F-22 Raptor engine.

“A cloud of thousands of bees” according to the 192nd Maintenance Squadron crew chief who was there.

Maintainers notified Capt. Katie Chiarantona, 192nd Aircraft Maintenance Officer about the honey bee swarm explains a USAF news release.

Since this had never happened on the flight line before, Chiarantona initially called the on-base entomologist to assess the situation. The entomologist immediately knew that he did not have the means to relocate the bees, so he referred Chiarantona to a local honey bee keeper in Hampton, Virginia.

Andy Westrich, U.S. Navy retired and local bee keeper, arrived on base with the needed materials and supplies. According to Chiarantona, Westrich said the swarm was one of the largest he had ever seen. He was escorted to the aircraft and used vacuum hoses to safely corral the honey bees off of the aircraft into large buckets. He then took the bee’s home and found that, as a hive, they weighed eight pounds which calculates to almost 20,000 bees!

“The honey bees most likely came from a much larger bee hive somewhere else on base,” said Chief Master Sergeant Gregg Allen, 192nd Maintenance Group Quality Assurance chief, who also happens to be a bee keeper. “Bee hives are constantly growing and they eventually become overcrowded. Around springtime, the bees will make a new queen, scout for a new location and take half of the hive with them to that location.”

Westrich suspected that the swarm of bees were on their way to a new location to build a hive for their queen. Queen bees typically fly with eggs to lay at the new hive and do not eat for up to 10 days before leaving to start a new colony. As a result, the queen is often malnourished for the journey. Westrich believes she landed on the F-22 to rest. Honey bees do not leave the queen, so they swarmed around the F-22 and eventually landed there.

According to Chiarantona “[Westrich] said that one out of two things could have happened, the queen would have rested and gained energy and the swarm would’ve left in the morning, or they would have decided that the jet engine would be a great place to build a hive.”

Westrich was able to safely relocate the colony to a local beer producer where they will maintain the honey bee colony and use the honey for their production facility.
“Every bee is important to our food source; lots of things would die without bees,” said Baskin. “Most of our crops depend on bees, and our bees need to pollinate. This is why I knew we needed to save them instead of [exterminate] them.”

This is the worst nightmare for pilots conducting trap landings on an aircraft carrier.

This video was filmed on Mar. 18, 2016 and shows an E-2C Hawkeye performing a trap landing on the flight deck of the USS Dwight D. Eisenhower.

As the footage shows, the cable used to catch the landing aircraft snapped: you can see the E-2C, slowed down by the #4 wire, continue toward the end of the flight deck, disappear off the flight deck while falling toward the sea before reappearing several seconds later, miraculously managing to gain speed and altitude.

According to the Virginian-Pilot media outlet, U.S. Navy investigators blamed human error and an improperly programmed valve for the incident in which eight sailors were injured.

Aircraft performing for an arrested landing on a carrier apply full throttle immediately after touchdown for two reasons: they may miss the cable or, worst case scenario, the cable might snap. In both cases, the aircraft needs to

Amateur tracking software can monitor the signals sent by the aircraft to the Inmarsat network.

On Mar. 8, 2014, Malaysia Airlines flight MH370, a Boeing B777-200 aircraft (registration 9M-MRO), operating from Kuala Lumpur and Beijing, disappeared from radars about 40 minutes after take off from Kuala Lumpur.

The flight, carrying a total number of 239 passengers and crew members, was regularly transmitting ADS-B data until contact was lost over the Gulf of Thailand, when the wide body was cruising at 35,000 feet at 474 knots in reportedly good weather.

Between 1:19 and 1:20AM local time, the aircraft turned right, changing heading from 25 to 40 degrees.

The transponder stopped transmitting at 1:21AM LT.

According to the Malaysian authorities, there were subsequent primary radar returns to the west of the Malaysian peninsula, over the Strait of Malacca and then north-west. This is assumed to be a real return from MH370 even if based on primary radar echo.

For reasons we still don’t know the aircraft radio systems did not work while the plane flew westwards back towards Malaysia.

Even if information was incoherent and sometimes contradictory, we know for certain that military radars in both Malaysia and Thailand saw the plane.

SATCOM (a radio system that uses a constellation of satellites used to transmit voice, data or both)  system pings linked to the INMARSAT network continued for 7+ (last ping at 08:11 local) hrs after LOS (loss of signal).

A Ping is a quite common term for IT Networking. It refers to a utility used to test the reachability of a host on an IP network and measure the round-trip time (RTT) of the packets even if it is more frequently associated to the data messages themselves, or “pings”.

Similarly to what happens on a Local Area Network, satellites send pings (once an hour) to their receiving peers that respond to it thus signaling their network presence. Hence, these pings are no more than simple probes used to check the reachability of SATCOM systems aboard the planes.

Based on the round-trip times of such pings, two arcs made of all the possible positions located at the same distance from the INMARSAT satellite were drawn.

But further analysis on Doppler Effect, as well as correlation among the “signatures” of other B777s, clearly indicated that aircraft had followed a southbound route, towards the South Pole.

Whilst search efforts have not been able to find the wreckage of the Boeing 777, the mysterious disappearance of the MH370 flight highlighted the need for tracking aircraft flying over high seas or remote locations, where radar coverage does not exist (such as southern Indian Ocean where aircraft, ships and submarines from 26 nations, have searched for any debris).

Two years on from the loss of MH370 and six months after Inmarsat completed their initial trials of a free tracking network for commercial traffic across Autralasia and the Pacific region COAA’s team who develop PlanePlotter, an aircraft position plotting program that decodes the digital messages transmitted from aircraft to display their content and plot their position on a radar-like chart, have successfully completed their own trials to see if we can obtain location data from the Inmarsat fleet and then plot it on their own tracking system.

Here’s how they describe their recent developments:

“This had been on our minds for some time, but we didn’t have the decoding knowledge to fully understand the signals from the satellite fleet,” says John, from PlanePlotter support.

“In stepped “Jonti” from New Zealand, who co-incidentally had been decoding the L band signals in the Aero band from Inmarsat. Those signals did not contain location data as the ACARS style messages at L band are from the earth stations, up to the satellite and “down” to the aircraft.

Thinking back to the days when we monitored the Inmarsat analogue phone circuits we realised that to get both sides of the “conversation” we needed to monitor both L band [ 1.5 ghz ] …and C [3.5 ghz] band. With Jonti’s help we set about some trials.

Inmarsat uses 8m dishes to monitor the tracking signals, we only had 1.8m and 2.4m dishes, but with Jonti’s guidance we managed to get good signals with just 1.8m antenna.

Jonti identified the short bursts of data which looked like they were from the a/c and after some stirling work he produced a version of his software JAERO, which decoded the bursts. Sure enough, in the data down from the aircraft was information akin to that which is contained in ADS-B signals. Using that and satellite dishes in Europe, America and Australasia we can now locate aircraft from the US
eastern seaboard into Asia and across the Pacific, via five different satellites.”

PlanePlotter are in the middle of further tests and have recently rolled out a new version of their software which, for their satellite ground stations, will provide full information, from location, heading etc. to outside air temperature: in fact, everything you would expect from ADS-B data.

“For our sharers it will show the usual ADS-B style information and plot sat comms equipped Oceanic traffic in real-time. Whilst we are not seeing reports from aircraft on a 15 minute basis yet, presumably as more airlines comply the reports will become more regular,” says John.

“Over the next few weeks more of our satellite ground stations will come online providing real-time coverage for tracking enthusiasts. The Inmarsat data, combined with ACARS, live PiReps and ADS-B will provide seamless global tracking.”

A passenger has caught on video a direct lightning strike on a Delta Boeing 737 at Atlanta airport.

The video below is extremely interesting. Shot at Atlanta airport during a thunderstorm by Jack Perkins, a passenger of another plane, it shows a lightning strike hit a Delta Boeing 737 on the taxiway.

No one was hurt as a consequence of the lightning as the plane is shielded by Faraday Cage, that blocks out external static electrical fields: charges redistribute on the conducting material and don’t affect the cage’s interior.

In simple words: if hit by a lightning aircraft let the current pass through the fuselage until ground, preserving the systems’ integrity. Furthermore, all commercial and military aircraft have been designed to meet several safety lightning-related requirements needed to get the airworthiness certifications required.

Generally speaking, lightning strikes are rare and do not represent a real threat to military and civil planes, even though, in the 1980s, some F-16 Fighting Falcon jets were lost after being hit. In one case, the lightning ignited the vapors in the empty centerline tank, which exploded causing extended damage to the aircraft’s hydraulic system.

If you thought that just dropping an inert weapon during a test to validate a specific platform or procedure was an easy and safe task, you were wrong.

The following video shows a series of catastrophic incidents caused by a bomb release or tank jettison gone wrong.

Impressive.

Weapons separations involving new aircraft, pylons, tanks or ordnance are always filmed to evaluate and prevent incident like those shown in the video.
