Maybe an email to the school is called for.
Looks like she has her face a bit closer to the vent than I'd recommend, are they lighting loose powder in the vent using a match or what? Point I want to make is that it might be a good idea to get some video of them firing a few rounds to see the whole procedure, and they are probably doing much scarier things than that, then a meaningful critique could be sent.
After I had some cannon shooting experinece and safety training, I photo-documented the US Naval Academy's firing of their original Dahlgren boat howitzer, and it was scary. The biggest issue was the quick-loading to get off a second shot for the extra point just after they'd already fired for a touchdown. There was no proper servicing of the bore and chamber, and the second shot was loaded within a few seconds of the firing the first. The crew had no formal training or knowledge, frankly, they just had the basic steps required to make the cannon go "bang" which were handed down thru a prestiege group known as "The Cannoneers." It was like a mini-fraternity, a social club.
To make a long story short I got my boss in the Navy Gun Division in Washington to sign out a letter to the Supt. of USNA. They didn't change much but a regular inspection of the gun by our experts at the Naval Surface Warfare Center at Dahlgren, VA was started, and the gun was eventually condemned for firing due to internal erosion under the vent.
We also got our Weapons Safety folks at Indian Head, MD to do an audit of training and procedures. At my recommendation they sent a gov't employee who was also a member of an artillery crew in the NSSA, and he was quite amazed at the lack of knowledge he found. All this ended the use of the original Dahlgren at USNA, and of any muzzle-loaders for football game salutes. Any breechloading salute gun is better for that in my opinion, and last time I checked, that's what USNA was using. No ramrod to get launched into the crowd, etc. If you check the record, many horrific accidents have happened at football games.
Many of those show up in The Artilleryman's periodic summary of accidents. I compiled all the Artilleryman's reports for about a 20-year period and send the package to our Weapons Safety group, and they in turn used it to shut down the unsafe practices at USNA. I hated to do all that since I went to school there, but I'd never feel right if anyone had been permanently injured when I could have prevented it.
